Throughout the continuing development of these products we have always striven to ensure that requirements in terms of fundamental performance features, electrical and mechanical service life, dimensions, and ease of installation and maintenance are met or exceeded. We have been able to meet the demands resulting from increased environ- mental awareness, particularly in the last ten years or so, by developing and using environment-friendly and recyclable materials. As a result, we have developed modern industrial switching devices, particularly in the field of low-voltage switchgear, that meet all the relevant demands in terms of envi- ronment-friendliness. Building on decades of experience, we have created a completely new gen- eration of circuit breakers, contactors, auxiliary contactors, overload relays, contactor relays, time relays, and 3RW3 semiconductor motor control devices (referred to below as soft starters) under the name SIRIUS for the large and continuously growing number of motor drives in the range up to 45 kW. These new SIRIUS devices fulfill all the demands placed on them in practice and can be used as stand-alone devices or modular components of com- plete load feeders, or integrated in low-voltage distribution cabinets or low- voltage switching stations.

GWA 4NEB 430 0999-02b 1-3 1.1 Specifications/regulations/approvals Explosion protection Motor protection devices that protect a motor from overload in a hazardous area must meet certain requirements. These requirements are defined in the following standards: DIN VDE 0660, DIN VDE 0165, EN 60947-1:1991..+A11:1994, EN 60947-4-1, EN 50014:1994, EN 50019:1978+A1 to A5 Compliance with these standards has up until now been established by means of a test. Compliance could be documented in two ways: 1. By a test certificate from the manufacturer 2. By a test certificate from an independent test laboratory (e.g. PTB, DMT, KEMA, etc.). EU directive Testing of explosion protection has been defined more precisely as a result of the harmonization of the European Union. In addition to the above stan- dards, tests will also carried out in acc. with the EU directive 94/9/EC or ATEX 100a. Two procedures are in operation during the transition period up until 2003: Procedure 1 Test certificate from an independent test laboratory as usual (e.g. PTB, DMT, KEMA, etc.). Procedure 2 Special test certificate from certified test laboratories (in acc. with extended European rules). The statutory basis for this is the Official Journal of the European Union (no. 95/C2 15/02 of 19.08.1995). Siemens SIRIUS switching devices are tested and certified twice: Certificate 1 Test certificate from KEMA in the same way as before (valid until 2003) in acc. with: • DIN VDE 0660, DIN VDE 0165 • EN 60947-1:1991/A11 • EN 60947-4-1:1992, EN 50019:1978+A1 to A5 Certificate 2 Special test certificate from the DMT-BVS in acc. with: • DIN VDE 0660, DIN VDE 0165 • EN 60947-1:1991..+A11:1994, EN 60947-4-1 • EN 50014:1994, EN 50019:1978 + A1 to A5 • EU directive 94/9/EC (ATEX 100a - EU directive)

1-4 GWA 4NEB 430 0999-02b DMT-BVS The DMT-BVS is, like the PTB, a certified German testing organization in compliance with the EU directive 76/117/EEC and EIExV. Like the PTB and other testing institutes in Europe, the DMT-BVS tests and awards certifi- cates in acc. with the explosion protection directive 94/9/EC and is accred- ited accordingly. Over 100 years ago, the DMT-BVS became the first testing station for explo- sion protection in Germany, and it has been a testing station for electrical equipment as well since 1912. DMT-BVS certificates are recognized through- out the world. For support in export matters, the DMT-BVS works with the chemical industry and is of course recognized by it. KEMA KEMA, which is a testing institute that enjoys worldwide recognition, is a certified European institute with many years of experience of testing for explosion protection. For support in export matters, KEMA also works with testing stations throughout the world.

GWA 4NEB 430 0999-02b 1-5 1.2 Overview: Range of devices SIRIUS system The SIRIUS product range consists of 3RV circuit breakers, 3RT contactors, 3RH/3RT auxiliary contactors and contactor relays, 3RU thermal overload relays, 3RB10/3RB12 electronic overload relays, 3RP time relays, 3RW3 semiconductor motor control devices (referred to below as soft starters), and combinations of these devices, which form the 3RA load feeders. The individual devices are developed and built in such a way that it is very easy to put them together to make load feeders. This is possible because the devices are all built to work together on both an electrical and a mechan- ical level. Figure 1-1: SIRIUS system NSB00296

1-10 GWA 4NEB 430 0999-02b 1.3 System features The entire SIRIUS range of devices is divided up into only four frame sizes (S00 up to 5.5 kW, S0 up to 11 kW, S2 up to 22 kW, and S3 up to 45 kW) with three different widths (45 mm for S00 and S0, 55 mm for S2, and 70 mm for S3) and has a uniform range of accessories for all frame sizes. Modular system The individual components of the SIRIUS range are building blocks in a mod- ular system that are harmonized in terms of both their frame size and their technical specifications. This ensures that individual requirements can be met quickly and cost-effectively. Uniformity The devices are harmonized with regard to their ratings and their technical specifications: • The same width ensures rapid installation. • The terminal systems are standardized, and devices with the same rated current have the same terminals. Performance capability All SIRIUS devices can be mounted side by side without derating in an ambi- ent air temperature of up to 60 °C. Accessories All accessories, such as the auxiliary switches and surge suppressors, can be mounted and removed without tools. You can use link modules that connect devices both mechanically and elec- trically to put together combinations of devices and build fuseless load feed- ers. Communication Direct communication with a higher-level controller is possible using: • The AS-Interface load feeder module • The ET 200X distributed I/O devices on the PROFIBUS-DP bus system • The ET 200S system

GWA 4NEB 430 0999-02b 1-15 1.5 Mounting methods and terminal systems 1.5.1 Mounting the equipment The method of mounting the equipment is uniform within each frame size. Table 1-2: Mounting methods Screw-on mounting The SIRIUS switching devices can be screwed on to a flat surface. Please note the following points with some of the devices: • 3RV1 circuit breaker, frame sizes S00/S0: Push-in lugs are required for screw-type mounting • 3RP15 time relay: Push-in lugs are required for screw-type mounting • Coupling links: No screw-type mounting • Soft starters: No screw-type mounting Snap-on mounting The SIRIUS switching devices are snapped onto 35 mm rails in acc. with DIN EN 50 022 without a tool. The devices with a frame size of S3 require a rail with an installation height of 15 mm. Alternatively, they can also be snapped onto 75 mm rails. Frame size Mounting Removal S00 to S3 Screwed on Removed with a screwdriver S00, S0 Snapped onto a 35 mm rail (in acc. with DIN EN 50 022) Removed without a tool S2 Snapped onto a 35 mm rail (in acc. with DIN EN 50 022) The snap-on spring can be opened with a screwdriver S3 Snapped onto a 35 mm rail (in acc. with DIN EN 50 022) Snapped onto a 75 mm rail The snap-on spring can be opened with a screwdriver

1-16 GWA 4NEB 430 0999-02b The following table shows you how to mount the device onto the rail: Table 1-3: Mounting the device on the rail The following table shows you how to remove the device from the rail: Table 1-4: Removing the device from the rail You will find notes on mounting the different devices on the rail in the rele- vant parts of section n.5 on mounting methods and terminal systems. Frame size Procedure Illustration S00/S0 Place the device on the upper edge of the rail, and press it down- wards until it snaps onto the lower edge of the rail. S2/S3 Place the device on the upper edge of the rail, and tilt it towards the rail until it snaps onto the lower edge of the rail. Frame size Procedure Illustration S00/S0 Push the device downwards to release the tension of the mounting spring, and remove the device by tilting it. S2/S3 Using a screwdriver, push the clip on the lower rear side of the device downwards to release the tension of the mounting spring (1), and remove the device by tilting it (2). 2 1 1 1 2

GWA 4NEB 430 0999-02b 1-17 1.5.2 Screw-type terminals The terminals used do not vary within a frame size. The current switched by the different devices of a single frame size does not vary either. This means you can use the same tool, torque, and conductor cross-section for the cir- cuit breakers, contactors, and overload relays of a single frame size. The stripped lengths are also the same. This is important in the case of prefabri- cated wiring. Screw-type terminals All the devices have screw-type terminals, either a terminal with a top washer or a box terminal, depending on the frame size. Devices with frame sizes S00 and S0 have terminals with captive screws and terminal washers that enable you to connect 2 conductors, even if they have different cross-sections. The box terminals of frame size S2 and S3 can also take 2 conductors with different cross-sections. Connection tools Use the following tools to make the connection: • Frame sizes S00 to S2: Screws are available for rated currents of up to 50 A for Pozidriv2 screwdrivers. • Frame size S3: To obtain the required torques for the frame size for up to 100 A, the screws have a 4 mm hexagon socket. The screwdriver guides allow screwdriving machines to be used. Lugs and connecting bars You can remove the box terminals from the devices with a frame size of S3 to connect conductors with lugs or connecting bars. A terminal cover is available as shock protection and to ensure that you comply with the required creepages and clearances when the box terminals are removed. You can find a detailed description in section n.4 on accessories.

1-18 GWA 4NEB 430 0999-02b 1.5.3 Cage Clamp terminals The Cage Clamp terminal system is now available for circuit breakers, con- tactors, overload relays, and time relays. Cage-type clamping units, known as Cage Clamp terminals in the case of SIRIUS products, facilitate quick and maintenance-free wiring. Design The Cage Clamp terminal consists of two parts: • A power rail for conducting current • A sprung cage-type clamp for clamping strength Figure 1-8: Cage Clamp terminal Conductors The Cage Clamp terminal on the switching devices clamps all copper wires (single-core, stranded and finely stranded) from 0.25 mm2 to 2.5 mm2. The conductors can be clamped directly or with some protection for splicing. To this end, wire end ferrules or pin-end connectors can be placed on the con- ductor ends. The best solution is an ultrasonically condensed conductor. Clamp Power rail Single-core Stranded Finely stranded Finely stranded with wire end ferrule

GWA 4NEB 430 0999-02b 1-19 Safety The devices are equipped with a two-wire connection. In other words, there are two independent connections for each conducting path. Only one conductor is connected to each clamping unit. The clamp presses the conductor against the power rail, which is curved at this point. The high specific compressive load thus achieved is gas-tight. The clamp presses its flat surface against the conductor, thus avoiding dam- age to it. The spring force of the clamp is designed so that it automatically adjusts to the radius of the conductor. This allows any deformation of the conductor to be dealt with. It is not possible for the clamping unit to loosen by itself. This connection is vibration- and shock-proof. These types of stress do not damage the conductor or cause any loss in contact. Machines and systems in which this type of stress occurs, such as vibrators and elevators, are particularly suitable applications for this connection. Transfer accuracy The contact pressure between the conductor and power rail is optimal, mak- ing this clamp terminal suitable for high-voltage installations and also for the transfer of voltages and currents in the mV and mA ranges in measuring technology and electronics. Tool Screwdrivers can be obtained from the NSK (low-voltage switchgear) cata- log for opening the Cage Clamp terminals. Procedure The following table shows you how to use the Cage Clamp: Table 1-5: How to use a Cage Clamp terminal Step Procedure 1 Insert the screwdriver into the rectangularopening until it stops. The screwdriver head auto- matically keeps the clamp open. 2 Insert the conductor into the oval terminal opening. 3 Remove the screwdriver. The terminal closes, and the conductor is thus secu- rely clamped. NSJ 00001 NSJ 00002 NSJ 00003

1-20 GWA 4NEB 430 0999-02b Small conductor cross- sections With conductor cross-sections that are ≤ 1 mm2, you have to use an insula- ting stop to ensure the conductors remain securely clamped. The illustration below shows the procedure: Figure 1-9: Conductor cross-sections ≤ 1 mm² 1.5.4 Connection cross-sections Because SIRIUS is a modular system, the connection cross-sections are the same for all devices of a single frame size. The following tables specify the permissible conductor cross-sections for main and auxiliary conductor connections: Frame size S00 Table 1-6: Connection cross-section for frame size S00 Frame size S0 Table 1-7: Connection cross-section for frame size S0 ≤ 1 mm² 3RT1916-4JA02 Main and auxiliary conductors ∅ 5 to 6 mm/PZ2 0.8 to 1.2 Nm 7 to 10.3 lb.in Cage Clamp 2 x (0.5 to 1.5 mm²) 2 x (0.75 to 2.5 mm²) 2 x (0.25 to 2.5 mm²) 2 x (0.5 to 1.5 mm²) 2 x (0.75 to 2.5 mm²) 2 x (0.25 to 1.5 mm²) ---- 2 x (0.25 to 2.5 mm²) AWG 2 x (18 to 14) 2 x (24 to 14) 10 10 10 Control conductor: A1/A2 Auxiliary conductor: NO/NC Main conductor Screw-type terminal Cage Clamp terminal L1 L2 L3 T1 T2 T3 ∅ 5 to 6 mm/PZ2 0.8 1.2 Nm 7 to 10.3 lb.in ---- 2 to 2.5 Nm 18 to 22 lb.in 2 x (0.5 to 1.5 mm²) 2 x (0.75 to 2.5 mm²) 2 x (0.25 to 2.5 mm²) 2 x (1 to 2.5 mm²) 2 x (2.5 to 6 mm²) 2 x (0.5 to 1.5 mm²) 2 x (0.75 to 2.5 mm²) 2 x (0.25 to 1.5 mm²) 2 x (1 to 2.5 mm²) 2 x (2.5 to 6 mm²) ---- 2 x (0.25 to 2.5 mm²) ---- AWG 2 x (18 to 14) 2 x (24 to 14) 2 x (14 to 10) 10 10 10

Commu- nication with the higher-level control system via open, PROFIBUS-DP, and AS-Interface connections. Actuator-sensor inter- face (AS-Interface) AS-Interface is a standardized, non-proprietary networking system (IEC 62026-2) for simple and usually binary actuators and sensors. It is pos- sible to connect it to SIMATIC programmable logic controllers via different master modules. A DP/AS-Interface link also ensures direct integration in a PROFIBUS-DP system or connection to other field buses via couplers. Up to 248 sensors and 186 actuators can be connected to an AS-Interface network over a maximum of 500 m. Safety-related signals can now also be net- worked with AS-Interface, thus dispensing with the wiring of emergency stop signals that was needed previously. PROFIBUS PROFIBUS is a standardized, non-proprietary field bus system (IEC 61158) to which most PLCs of leading manufacturers can be connected. Up to 125 nodes can be incorporated in one bus segment. Distances of up to 9.6 km can be bridged with copper cables and up to 100 km with fiber-optic cables. S7-300 M 3 M 3 M 3 NSA00001b AS-Interface M 3 LOGO!

GWA 4NEB 430 0999-02b 1-23 PROFIBUS-DP PROFIBUS-DP (DP being a German abbreviation for distributed I/O) is used for switching devices with higher communication requirements (e.g. the transmission of analog actual values with extremely fast response times). It is also used to link individual AS-Interface segments. 1.6.2 Parameterization of PROFIBUS-DP and bus-capable low-voltage switching devices Before commissioning, PROFIBUS-DP must be configured, and the individ- ual bus nodes must be parameterized. There are user-friendly tools available to the user for configuration and parameter assignment. Parameter assignment tools • For SIMATIC S7 masters, all the functions are integrated in the STEP 7 programming language. • For SIMATIC S5 masters and various non-Siemens masters, the COM PROFIBUS parameter assignment software is required. • Manufacturers of non-Siemens masters offer other configuration and parameter assignment programs. Applications The above program packages make it easy to carry out the following for PROFIBUS-DP and its nodes: • Configuration • Parameter assignment • Documentation • Commissioning • Testing • Diagnostics For additional information on communication-capable low-voltage switching devices, as well as system components and accessories, see the following catalogs: • ST 70 "S7, M7 and C7 Programmable Logic Controllers" • IK PI "Industrial Communication and Field Devices" 1.6.3 Actuator-sensor interface (AS-Interface) The actuator-sensor interface (AS-Interface) is a modular networking system for sensors and actuators in the lowest field range. It makes no difference to the program in the programmable controller whether parallel wiring with input/output modules or AS-Interface is used. It is therefore possible for existing systems to change to AS-Interface because you can continue to use the same programs. The entire system can be oper- ated without additional software. It is not necessary to be familiar with the internal workings of AS-Interface.

1-24 GWA 4NEB 430 0999-02b Replacement for the cable harness Process signals that occur in situ, are normally transferred to the open loop control using extensive parallel wiring and input/output modules. This means that each sensor or actuator in the field is connected to the input/ output modules with its own cable. AS-Interface makes it possible to replace this cable harness with a simple two-wire cable for all sensors or actuators. Data and power on a two-wire cable The master communicates with the nodes via the AS-Interface cable. As well as data, this cable also transfers the supply voltage for the electronic components and sensors. The voltage is supplied to the AS-Interface cable from a special AS-Interface power supply unit with a data link. Setting up different structures The AS-Interface cable is laid in the same way as for an electrical installa- tion. A new feeder can be inserted at any point. This makes it possible to set up network structures (e.g. tree, star or line structures). No shielding or ter- minating resistors are required. The wiring can be adapted individually to the system or machine. Detailed configuration and installation guidelines can be found in the instal- lation guideline "Montage des Vernetzungssystems AS-Interface" (on mount- ing the AS-Interface networking system). Maximum system con- figuration Up to 62 nodes can be connected to the AS-Interface cable. A node is, for example, an AS-Interface module (digital or analog) or a BERO (proximity switch) with an integrated AS-Interface chip. A maximum of 4 binary stan- dard sensors and/or 4 actuators can be connected to an AS-Interface mod- ule. This produces a maximum configuration of 248 sensors and 186 actuators (62 nodes x 4 inputs and 3 outputs). IP 67 degree of protection AS-Interface is a networking system for direct use on the machine. The AS- Interface user compact modules have IP 67 protection. They can be used in situ without being enclosed. There are also AS-Interface modules for use with IP 20 protection in the cubicles or distributed switchboxes.

GWA 4NEB 430 0999-02b 1-25 New installation system All compact modules are placed on a mounting plate. The mounting plate takes the AS-Interface cable and keeps it in place. Polarity reversal is not possible due to the profile of the cable. The compact modules are simply hooked on at the top of the mounting plate and secured with just one screw. When you secure the modules, contact is made with the AS-Interface cable. You do not have to strip or screw on the cable. Coding prevents errors All the modules are mechanically and electrically coded. The coding system prevents errors occurring in the event of replacement. At replacement, only one module of the same type can ever be mounted. This stops digital or analog modules (or even inputs or outputs) getting mixed up. Addressing To participate in data transfer with the master, each node must be assigned an address before commissioning of the AS-Interface network. Addressing devices are available for this. Addressing an installed module There is an additional feature which makes new Siemens modules even more user-friendly: the addressing socket. Using this socket you can address a module after it has been installed. It is not necessary to unscrew the module. Installation can be carried out in the system by personnel who are not familiar with the AS-Interface. The com- missioning engineer can address the modules easily when they are already installed. For the first time, this type of addressing is also possible with IP 67 protection. Diagnostics at a glance The new generation of AS-Interface modules (compact modules, analog modules, and SlimLine modules) has the new display system developed by Siemens. The status of a module is displayed by two LEDs lighting up continuously or flashing. This simple diagnostic feature directly on the module makes it possible for the user to find the error quickly and efficiently. This in turn reduces down- times. Certificates of the AS- Interface association All Siemens AS-Interface products are tested in acc. with the relevant testing regulations in an accredited test laboratory and certified by the AS- Interface association.

1-26 GWA 4NEB 430 0999-02b Digital compact mod- ules with IP 67 protection The AS-Interface modules in the compact range are characterized by opti- mized operating features and improved user-friendliness. This can reduce mounting and commissioning times for AS-Interface by up to 40%. Additional LEDs provide information on the most important operat- ing modes of the module, resulting in a considerable increase in system availability. The modules of the compact range consist of two components: Mounting plate and compact module The mounting plate mechanically fixes the AS-Interface profile cables, takes the compact module, and serves as a template with drill holes. The compact module contains the electronic components for communica- tion and the M12 standard connections for inputs/outputs. Up to four sen- sors and four actuators can be easily and reliably connected to the compact module using the M12 standard connection. The mounting plate and compact module are only connected to each other by means of a single screw. Contact is established with the AS-Interface cable by means of the proven insulation displacement method. AS-Interface modules in the compact range that have an M12 connection can have a protective conductor (PE) connected to them. Using an addressing socket integrated in the compact module, you can also allocate addresses when the module is in place. Analog compact mod- ules with IP 67 protection The design of the analog modules has been adapted for the compact mod- ules. The analog input and output modules each have two channels. You can connect measuring sensors and analog actuators using standard M12 con- nectors. The following groups of analog modules exist: • Input module for two current sensors • Input module for two voltage sensors • Input module for two thermal resistors • Output module for two current actuators • Output module for two voltage actuators All the measured values - except for the thermal resistance value of Pt 100 (not linear) - are available in linear form. In other words, the non-linear trans- mission curve of the thermal resistor sensor is automatically linearized in the analog module, and measured values can be processed directly in the programmable controller. The input and output channels are isolated. Two-wire and four-wire sensors can be connected. Differential inputs produce considerable suppression of common-mode interference. The integrating sigma-delta converter ensures high measurement accuracy.

GWA 4NEB 430 0999-02b 1-27 Pneumatic compact modules with IP 65 and IP 67 protection The pneumatic compact module is a highly integrated AS-Interface slave. As an input/output module that is entirely suitable for field deployment, it has four electrical inputs and two pneumatic outputs. The electrical inputs behave in the same way as the inputs of the digital input/output compact modules. Both integrated pneumatic outputs are implemented by means of two pre- set 4/2-way valves (2 to 8 bar; 550 Nl/min) with a shared compressed-air supply and separate exhaust air collection and can be operated manually using separate slide valves. Two cylinders that work in tandem, for example, can be connected to a module in this range. Connections to AS-Interface are made via the standard mounting plate. The AS-Interface cable is inserted into the corresponding cable guides, and the upper part is secured to the mounting plate by means of a screw. The mod- ule is ready for use. Safety first - emergency stop via AS-i AS-Interface is the first system on the market that can transmit both stan- dard signals and safety-related input signals (e.g. emergency stop) via the same cable. Only an additional safety monitor and safe modules are required to use AS- Interface as a safety bus. This enables category 4 in acc. with EN 954-1 to be achieved. A failsafe programmable controller or special master is not nec- essary. The concept and implementation of AS-Interface Safety at Work (AS-Inter- face SaW) have been tested and certified by TÜV (technical testing associa- tion). This means that the system can be converted to the considerably more flex- ible AS-Interface network, which is already available, thus obviating the need for the complex, separately implemented emergency stop wiring that has been necessary up to now.

SIRIUS System Manual GWA 4NEB 430 0999-02b 2-5 2.2 Device description 3RV1 circuit breakers are used to switch and protect three-phase induction motors of up to 45 kW at 400 VAC and for loads with rated currents of up to 100 A. The 3RV1 circuit breakers have 3 poles. To achieve the highest degree of flexibility, auxiliary switches, alarm switches, auxiliary releases, and other accessories can be easily attached to the circuit breakers without tools, as required. 3RV1 circuit breakers and 3RT1 contactors are built to work together on both an electrical level and physically. This enables them to be easily and quickly put together to make load feeders. Frame sizes 3RV1 circuit breakers are available in 4 frame sizes (S00 to S3). Figure 2-1: 3RV1 circuit breakers (frame sizes S00 to S3) The following table shows you the frame sizes and the corresponding maxi- mum rated operational current at a voltage of 400 VAC. The last column in the table tells you which three-phase induction motor is suitable for which particular size.

SIRIUS System Manual 2-6 GWA 4NEB 430 0999-02b 2.2.1 General description Fields of application The 3RV1 circuit breakers are suitable for: • Motor and plant protection • Transformer protection • Starter protection (short-circuit protection) The 3RV16 11-0BD10 circuit breaker, frame size S00, is used for fuse moni- toring. Releases 3RV1 circuit breakers have: • Inverse-time delay, thermal overload releases • Instantaneous short-circuit releases The overload releases can be set to the load current. The short-circuit releases are set permanently to 12 times the rated current, which allows motors to start up without problems. Circuit breakers used for transformer protection are set to 19 times the rated current to avoid being tripped by the high inrush current. When the circuit breakers are tripped, in the case of frame size S00 the tog- gle switch goes into the tripped position, and in the case of frame sizes S0 to S3 the rotary switch switches to the tripped position. Before it is switched on again, the rotary switch must be put in the 0 position manually to avoid switching to the fault inadvertently. In the case of circuit breakers with a rotary switch, the tripping operation can also be reported electrically by means of an alarm switch. Tripping classes In acc. with IEC 947-4-1: • Frame sizes S00 to S3: class 10 • Frame sizes S2/S3: class 20 Auxiliary release The circuit breakers can also be equipped with one of the following auxiliary releases: • Shunt release • Undervoltage release • Undervoltage release with leading auxiliary contacts Auxiliary contact ele- ments The circuit breakers can be equipped with a transverse auxiliary switch, an electronically optimized transverse auxiliary switch or a lateral auxiliary switch (Section 2.4 Accessories). Shock protection Shock protection can be improved by covering the terminals and connec- tions. This can be achieved with the following accessories: • Frame size S00, S0: protective caps for transverse auxiliary switches • Frame size S2, S3: terminal covers for box terminals • Terminal covers for lug and bar connection

SIRIUS System Manual GWA 4NEB 430 0999-02b 2-9 Switches The state of the circuit breakers can be determined by the position of the switches: Table 2-2: Contact position indicators of the circuit breakers Figure 2-4: Tripped position, 3RV (frame size S0) Locking the circuit breakers You can prevent the circuit breaker from being switched on by unauthorized persons by securing the switch drive (toggle switch or rotary switch) with a padlock (shackle diameter 3.5 to 4.5 mm). Figure 2-5: Locking the toggle switch (frame size S00) Reclosing after a tripping operation After the circuit breaker has been tripped, the switch goes into the tripped position to indicate this. You use the switch to close the circuit again. In the case of frame sizes S0 to S3, the rotary switch must be put in the OFF position manually before it is switched on again to avoid switching to the fault inadvertently. In the case of frame sizes S2 and S3, it is possible to switch on and off using a motorized remote-control mechanism (see Section 2.4, Accessories).

SIRIUS System Manual 2-10 GWA 4NEB 430 0999-02b Testing overload tripping The following table shows you how overload tripping of the circuit breaker is tested: Table 2-3: Testing overload tripping (example: frame size S00) 2.2.3 Information on configuration Short-circuit protection The short-circuit releases of the 3RV1 circuit breakers execute a three-phase isolation of the faulty load feeder from the network and prevent any further damage. With a short-circuit breaking capacity of 50 kA or 100 kA and a voltage of 400 VAC, the switches are considered to be short circuit-proof, since hig- her short-circuit currents are not to be expected where the switches are installed. Backup fuses are only required if the short-circuit current at the point of installation exceeds the rated short-circuit breaking capacity of the circuit breakers. You will find the short-circuit breaking capacity for other voltages and the size of any required fuse listed in Section 2.6, Technical specifications. Conditions of applica- tion 3RV1 circuit breakers are climate-proof. They are intended for use in closed areas where there are no harzardous operating conditions such as dust, cor- rosive fumes or destructive gases. Appropriate housings are available as an accessory for use in dusty and damp areas (see Section 2.4). Inrush current Because the operational currents, the starting currents and the current spikes vary on account of the inrush current, even in motors of the same power, the motor powers listed in the tables are only guide values. Most important when selecting the correct circuit breakers are the concrete start- ing data and rating of the motor to be protected. This also applies to circuit breakers used for transformer protection. Drawing Step Procedure 1 Switch the toggle switch/rotary switch from 0 to 1. 2, 3 Put a screwdriver in the test opening and push it to the left. Overload tripping is in working order when the toggle switch switches from 1 to 0 (frame size S00) or goes into the trip- ped position (frame sizes S0 to S3). 2 3 1

SIRIUS System Manual GWA 4NEB 430 0999-02b 2-11 Phase loss sensitivity The phase loss sensitivity of the circuit breaker ensures that it is tripped in good time in the event of the loss of a phase and the resulting overcurrents in the other phases. During normal operation, the device should have a three-pole load. To pro- tect single-phase loads or direct current loads, all 3 main conducting paths should be switched in series. Explosion protection Note In the case of a three-pole load, at 5 to 8 times the set current, the release time deviates by a maximum of ± 20% and therefore complies with the requirement of DIN VDE 0165 and EN 50019: 1977 +A1 to A5 and DIN VDE 0165. Characteristics The tripping characteristic of the inverse-time delayed overload release (thermal overload release, a-release) is valid for direct current and alternat- ing current with frequencies of 0 to 400 Hz. The characteristics are valid for tripping operations from a cold state. From a warm state, the release times of the thermal releases are reduced to approximately 25 %. The tripping characteristics of the instantaneous electromagnetic overcur- rent releases (short-circuit release, n-release) is based on the rated current In, which in circuit breakers with adjustable overload releases is also the upper value of the adjustment range. The following is a chart of the time-current characteristic: Figure 2-6: Time-current characteristic, chart Time-current characteristics, current-limiting characteristics and I2t characte- ristics can be requested directly from your sales representative, if neces- sary. 10 5 2 1 10 000 5000 2000 1000 500 200 100 50 20 10 5 0,2 1 0,5 0,02 0,1 0,05 0,002 0,01 0,005 100 60 40 2 0,6 0,8 1 2 3 4 6 8 10 0,001 20 30 40 80 x n NSB00004 min s A 60 current opening time three-pole load class 20 three-pole load class 10 two-pole load class 10

For lower frequencies, such as 16 2/3 Hz, for higher frequencies up to 400 Hz, and for direct current, appropriate correction factors have to be taken into account. The following characteristic curve illustrates the frequency sensitivity of the short-circuit releases (calibrated to 12 times Iu +20%): Figure 2-7: Frequency sensitivity of the n-short-circuit releases The increase in tripping current is approximately 30% for DC voltage.

SIRIUS System Manual GWA 4NEB 430 0999-02b 2-13 2.3 Field of application/variants The tripping characteristics of the 3RV1 circuit breakers are designed prima- rily to protect three-phase induction motors. The circuit breakers are therefore also referred to as motor protecting switches. The 3RV1 circuit breakers for motor protection are limited to the protection of systems. 2.3.1 Motor protection Set current The current of the motor that is to be protected is set on the adjustment scale. The short-circuit release is set at the factory to 12 times the value of the rated current of the circuit breaker. This ensures problem-free startup and reliable protection of the motor. Phase loss sensitivity The phase loss sensitivity of the circuit breaker ensures that it is tripped in good time in the event of the loss of a phase and the resulting overcurrents in the other phases. CLASS10/CLASS20 Circuit breakers of frame sizes S00 to S3 with thermal overload releases comply with tripping class 10 (CLASS 10). Circuit breakers with the CLASS 20 tripping characteristic are available for frame sizes S2 and S3 in difficult startup conditions. 2.3.2 Transformer protection Inrush current In the case of primary protection of control transformers, the high inrush currents that occur when the transformers are switched on often result in the unwanted tripping of the protective devices. The 3RV1 circuit breakers with frame sizes S0 and S2 therefore have over- current releases for the protection of transformers that are set at the factory to approximately 19 times the rated current. This makes it possible to pro- tect transformers in which the inrush currents reach peak values of up to 30 times the rated current with circuit breakers in the primary circuit. In the case of 4AM control transformers with low inrush current (Siemens control transformers, for example), this is not required. 3RV1 circuit brea- kers can be used here for motor protection. 2.3.3 Starter protection The 3RV13 starter protection switches are circuit breakers without overload releases. They are used together with a contactor and overload relay if the circuit breaker is not to be triggered in the case of overload tripping.

SIRIUS System Manual 2-14 GWA 4NEB 430 0999-02b 2.3.4 Circuit breakers with overload relay function Circuit breakers with the 3RV11 overload relay function are available for frame sizes S0, S2, and S3. Description Circuit breakers with the overload relay function contain overload releases that do not affect the breaker mechanism of the circuit breakers. In the event of an overload, the circuit breaker remains switched on. To protect the following loads, 2 auxiliary contacts (1S + 1Ö) are attached on the right side. These are operated in the event of an overload. The auxiliary switch function can be evaluated or used to disconnect a downstream con- tactor. After the circuit breaker has cooled down, the auxiliary contacts are reset automatically. Caution In the overload range, the circuit breaker does not protect itself with the overload relay function. You must therefore ensure that the circuit breaker is safely disconnected by means of a downstream switching device (e.g. a contactor). Fixed link: auxiliary contacts with circuit breaker Note: The auxiliary contacts are connected to the circuit breaker on the right side and cannot be removed. Diagrams Figure 2-8: Circuit breaker with overload relay function (frame sizes S0 to S3) 2.3.5 Fuse monitoring The 3RV16 11-0BD10 circuit breaker is used with frame size S00 for fuse monitoring. A conducting path of the circuit breaker is switched in parallel for each fuse. If one fuse fails, the current flows via the parallel-switched conducting path of the circuit breaker and trips it.

SIRIUS System Manual GWA 4NEB 430 0999-02b 2-15 Warning Fuse monitoring using the 3RV16 11-0DB10 circuit breaker is not permissible in feeders with power control regulators where a DC feedback with higher values can occur in the event of a fault. Auxiliary switch func- tions The circuit breaker used for fuse monitoring can be equipped with a trans- verse or lateral auxiliary switch (Section 2.4, Accessories). The auxiliary switch reports the tripping of the circuit breaker and thus the failure of the fuse and initiates an all-pole disconnection of the problem circuit by a corre- sponding switching device. Safety sign Note When fuses used for isolation purposes are monitored, a warning sign must be put up next to them. Via the parallel-switched voltage circuit of the moni- toring facility, voltage may get into the area that is supposed to be isolated if the monitoring equipment has not bee disconnected. We suggest the following text for the warning: Voltages The 3RV16 11-0DB10 circuit breaker is suitable for fuse monitoring in the fol- lowing voltage ranges: • 24 to 690 VAC, 50/60 Hz • 24 to 250 VDC, 100 to 600 VDC Switching capacity ICN 100 kA Circuit diagrams Figure 2-9: Circuit diagrams of circuit breakers for fuse monitoring Attention To ensure isolation, also disconnect the fuse-monitoring device with the item designation ............

SIRIUS System Manual 2-16 GWA 4NEB 430 0999-02b Parallel cables/meshed networks Attention In the case of parallel cables and meshed networks, a tripping operation and report only occurs when the voltage difference at the circuit breaker is at least 24 V. 2.3.6 Switching direct current The 3RV1 circuit breakers for alternating current are suitable for switching direct current. However, you must note the maximum permissible DC volt- age per conducting path. In the case of higher voltages, series connection of 2 or 3 conducting paths is required. Response thresholds The response thresholds of the overload releases remain unchanged. The response thresholds of the short-circuit releases are increased with direct current by approximately 40%. The following table lists suggestions for switching direct current: Double ground fault Note In the case of the circuit with 2-pole switching and an ungrounded system, it is assumed that even in the event of a double ground fault that bridges two contacts, safe disconnection still occurs.

Variants: • 1 changeover contact • 1 NO + 1 NC contact • 2 NO contacts Width of the cir- cuit breaker remains the same Front Electronically optimized trans- verse auxiliary switch One transverse auxiliary switch can be attached for each circuit breaker: Variants: • 1 changeover contact Lateral auxiliary switch One lateral auxiliary switch can be attached for each circuit breaker: • 1 NO + 1 NC contact • 2 NO contacts • 2 NC contacts • 2 NO + 2 NC contacts 9 mm 18 mm Left side Alarm switch Frame sizes S0, S2 and S3 One alarm switch can be attached at the side of the circuit breakers with rotary switches. The alarm switch has two contact systems: • One contact system (1 NO + 1 NC) reports a general tripping operation, irrespective of whether it was caused by a short circuit, overload or auxiliary release. • The other contact system (1 NO + 1 NC) only switches in the event of a short circuit tripping operation. To reclose the circuit breaker after a short circuit, the alarm switch must be reset manually after the cause of the error has been elimi- nated. 18 mm Shunt release Remote release of the circuit breaker: • Via PLC: The coil of the release should be connected to the voltage only briefly • Especially suitable for emergency stop disconnection by means of appropriate emergency stop switches in acc. with DIN VDE 0113 18 mm Right side Accessories cannot be attached on the right of a circuit breaker with a relay func- tion. Undervoltage release Trips the circuit breaker in the event of a voltage interruption (e.g. when the power plug is removed) and prevents the motor starting up inadvertently when the voltage returns. Undervoltage release with lea- ding auxiliary con- tacts 2 NO Function and use, see undervoltage release. Additional function: The auxiliary contacts isolate the undervoltage release from the power system on both sides in the event of breaking or a tripping operation and thus prevent voltage distortion to the control circuit when the switch is in the off position. It is possible to reclose the circuit breaker because the contacts reclose.

SIRIUS System Manual GWA 4NEB 430 0999-02b 2-19 Table 2-5: Attachable accessories 2.4.2 Auxiliary switch, alarm switch, and auxiliary release The maximum configuration for each 3RV1 circuit breaker is one transverse auxiliary switch, one lateral auxiliary switch, one alarm switch, and one aux- iliary release. Possible combinations The following combinations of auxiliary switches and alarm switches or of auxiliary switches are possible: • Auxiliary and alarm switches can be installed individually or together. The lateral auxiliary switch is installed on the left of the alarm switch. • Transverse and lateral auxiliary switches can be combined. • One auxiliary release can be attached on the right for each circuit breaker: Mounting the auxiliary switches The auxiliary switches, alarm switches, and auxiliary releases are mounted in the same way for all frame sizes: Transverse auxiliary switch (3RV1901-1D, -1E, -1F) Figure 2-10: Mounting the transverse auxiliary switch (frame size S00) Accessories Function/use Width Attach to Disconnecting module Frame sizes S0 and S2 The supply is fed to the circuit breaker via the disconnecting module. A connector which can only be removed when the circuit breaker is switched off isolates the circuit breaker from the power system on 3 poles. The shock-protected isolation position is easily visible and is secured by a padlock to ensure that the connector cannot be used during maintenance work, for example. Width of the cir- cuit breaker remains the same Upper side Motorized remote-control mechanism For frame sizes S2 and S3 The circuit breakers can be opened and closed via the remote-con- trolled mechanism by means of electrical commands. This enables a load or system to be disconnected from and then reconnected to the power system from an operator control panel. The circuit breaker can be disconnected from and reconnected to the remote-control mechanism in situ. Rotary switch extension for the door The rotary switch extension for the door consists of a knob, a drive coupling and an extension shaft. They comply with IP 65.

SIRIUS System Manual 2-42 GWA 4NEB 430 0999-02b Combination of frame sizes S00 and S0 Circuit breakers in frame sizes S00 and S0 vary in height and depth and therefore cannot be combined on one busbar. You can combine two busbars for circuit breakers in frame sizes S0 and S00 using an extension piece. Extending the bus It is possible to extend the busbars by clamping the connecting lugs of a fur- ther bus (turned 180°) under the terminals of the last circuit breaker (see the section on mounting). Attention Note the current-carrying capacity of the busbars when you extend them. Accessories The following accessories are available for the isolated 3-phase busbar sys- tem: • Feed-in terminal from above (3RV1915-5A for S00, 3RV1925-5AB for S0, 3RV1935-5A for S2) • Feed-in terminal from below (3RV1915-5B for S00, S0) • Connector A connector links two 3-phase busbars over a space of 45 mm for circuit breakers in frame sizes S00 and S0. • Protective cap for connecting lugs (3RV19 15-6AB) Protective caps provide shock protection for spare slots. To extend the bus, remove the protective caps. • Spacer Feed-in terminal 3-phase feed-in terminals make it possible to have greater conductor cross- sections than on the circuit breaker itself. Tightening torque: 2 to 4 Nm (17.6 to 35.2 LB.IN). Feed-in terminal - con- nection from below Attention The feed-in terminal with connection from below is clamped on instead of a circuit breaker.

Screw-type terminals 3RV1 circuit breakers with frame sizes S00 and S0 have terminals with cap- tive screws and terminal washers that enable you to connect 2 conductors, even if they have different cross-sections. The box terminals of the circuit breakers of frame sizes S2 and S3 can also take 2 conductors with different cross-sections. With the exception of circuit breakers of frame size S3, which have terminal screws with a 4 mm Allen screw, all the terminal screws can be tightened using a standard screwdriver or a Pozidriv screwdriver (size 2). You can remove the box terminals from circuit breakers with a frame size of S3 to connect conductors with lugs or connecting bars. A terminal cover is available as shock protection and to ensure that you comply with the required creepages and clearances when the box terminals are removed. Soldering pin connec- tor Circuit breakers in frame size S00 can be soldered onto printed circuit boards by means of a soldering pin connector. A soldering pin connector is available for the main contacts and the transverse auxiliary switch.
