6 According to UL 89/IEC 697- for AC up to 5 A General data Benefits Low space requirements The SENTRON 3WL5 devices require very little space. Size I devices (up to 6 A) fit into a mm wide switchgear panel. Size III devices (up to 5 A) are the smallest of their kind and with their construction width of 7 mm fit into a 8 mm wide switchgear panel. Modular design Components like auiliary trip units, motorized operating mechanisms, electronic trip units, current sensors, auiliary circuit signaling switches, automatic reset devices, interlocks or engagement operating mechanisms can all be echanged or retrofitted at a later stage, thus allowing the circuit breaker to be adapted to new, changing requirements. Retrofittable modules for electronic trip units Modularity is one of the main features of the new SENTRON 3WL5 circuit breakers. Special LCDs, ground-fault modules, rated current modules and communication modules for the electronic trip units are available for fast and easy retrofitting and adaptation to changing requirements. Communication The use of modern communication-capable circuit breakers opens up completely new possibilities in terms of start-up, parameterization, diagnostics, maintenance and operation. This allows many different ways of reducing costs and improving productivity in industrial plants, buildings and infrastructure projects to be achieved. Timely information and response can prevent plant stoppages Effective diagnostics management Measured values are the basis for efficient load management, for drawing up power demand profiles and for assigning energy to cost centers reventive maintenance reduces the risk of epansive plant down-times Application As incoming-feeder, distribution, tie, and outgoing-feeder circuit breakers in electrical installations For switching and protecting motors, capacitors, generators, transformers, busbars and cables Due to the reinforced use of electronic I&C systems, the demands made on air circuit breakers in terms of operator control and monitoring of network processes have increased. The etensive, coordinated SENTRON range of devices covers all applications between 6 A and 5 A with compact and air circuit breakers. Standards SENTRON 3WL5 circuit breakers comply with: UL 89 IEC 697- DIN VDE 66 art Climate-proof according to IEC /6 Siemens LV 6 9

36 According to UL 89/IEC 697- for AC up to 5 A General data Electronic trip units (ETU) The electronic trip unit is controlled by a microprocessor and operates independently of an auiliary voltage. It enables systems to be adapted to the different protection requirements of distribution systems, motors, transformers and generators. Communication capabilities The international standard ROFIBUS D or MODBUS can be used to transmit data such as current values, switching states, reasons for tripping etc. to central computers. Data acquisition and energy management are possible in conjunction with the lus measurement function. A new internal circuit breaker data bus allows switchboard panel communication between the circuit breaker and secondary devices in the circuit breaker panel: Actuation of analog displays Facility to test the communication build-up with circuit breakers Display of tripping state and tripping reasons Input module for reading in further switchgear panel signals and for transmission of these signals to the ROFIBUS D or MODBUS Various output modules for displaying measured values. This means that it is not only possible to monitor the device remotely, but also to transmit current values from the entire system and perform switching operations remotely. I t and I t characteristic curve for overload protection The best protection for the whole switchgear is achieved by setting the tripping characteristic curve to an optimum value. In order to achieve optimal discrimination for upstream fuses or medium voltage protection systems, the inclination of the characteristic curve can be selected for the overload range. The overload protection L (long time protection) for the electronic trip units ETU5B allows the characteristic curve to be switched between I t and I t. The I t characteristic improves discrimination for downstream circuit breakers and fuses. Electronic trip units ETU Modularity has also been strictly emphasized during the development of the electronic trip units. These are some of the modules which can be easily retrofitted at any time: Ground-fault protection module Communication Measurement function Display Rated current module (Rating lug) This allows quick adaptation to new local mains specifications. In addition, innovative functions have been included in the ETUs. Rated current module/ rating plug Ground-fault protection module (retrofittable) Eample of configuration for ETU5B Tripped indicator/ Reset button LCD alphanumeric with 5 inclination and rotatable through 8 Sliding-dolly for switchable overload characteristic curve Rated current modules / Rating plugs The rated current module is an echangeable module which allows the user to reduce the rated device current so as to adapt it optimally to the plant; e.g. if a new plant section is taken into operation.

40 According to UL 89/IEC 697- for AC up to 5 A General data Configuration Mutual mechanical circuit breaker interlocking The module for mutual mechanical interlocking can be used for one or two SENTRON 3WL5 circuit breakers and can be adapted easily to the corresponding versions. The fiedmounted and withdrawable circuit breaker versions are fully compatible and can therefore be used in a mied configuration in an installation. The circuit breakers can be mounted alongside each other or one above the other, whereby the distance of the circuit breakers is determined solely by the length of the Bowden wire (lengths: m/3 m/.5 m). Interlock signals are looped through using the Bowden cables. Interlocking is only effective in the connected position in the case of withdrawable circuit breakers. The mechanical endurance of the Bowden cables is operating cycles. Minimum requirements must be fulfilled in the switchgear for the interlocking to function: Bowden cables must be installed as far as possible in a straight line with minimum bending. Mutual mechanical interlocking of circuit breakers eamples The bending radii of the Bowden wire must be greater than 5 mm. The sum of all bending angles along the Bowden wire must not eceed 6. In a vertical arrangement of circuit breakers to be interlocked, the interlocking mechanisms must be in line. Circuit breakers to be interlocked must be arranged so that Bowden cables can be optimally installed in compliance with the conditions mentioned in the above points. The installed Bowden cable must be fied (with cable ties or the like) before the interlock is adjusted. Select the width of switchgear cubicle to allow enough freedom of movement for adjusting the interlock Openings and cut-outs in system elements must be designed so that Bowden cables are not changed in direction or obstructed when they are passed through.

An integrated and modular communication architecture was designed for the SENTRON 3WL5 to ensure that it can satisfy these requirements. The core component of this architecture is the CubicleBUS, which links together all of the intelligent components within the SENTRON 3WL5 and enables the easy and safe connection of other additional eternal components to the circuit breaker. The CubicleBUS is already incorporated and pre-connected in all complete circuit breakers with ETU5B trip units. The high level of modularity of the system allows communication functions to be retrofitted at any time (e.g. the measurement function). Similarly, the upgrade of a non-communication-capable SENTRON 3WL5 (e.g. changeover from ETU5B to ETU5B with CubicleBUS) can be carried out easily on site in the plant. All modules connected to the CubicleBUS can directly access the eisting source data of the circuit breaker, which guarantees the quickest possible access to information and response to events. Furthermore, additional eternal modules (including digital inputs/ outputs, analog outputs) can be connected to the CubicleBUS to provide cost-effective solutions for the automation of further devices in the switchgear.

44 According to UL 89/IEC 697- for AC up to 5 A General data CubicleBUS modules Digital output modules with rotary coding switch 6 items of binary information concerning the state of the circuit breaker (reasons for tripping and warnings) can be output via this module to eternal signaling devices (e.g. LED, horn) or be used for the selective shut-down of other system components (e.g. frequency converters). Digital output modules are available in versions with and without a rotary coding switch. On modules with a rotary coding switch it is possible to choose between two signaling blocks each with 6 defined assignments and to set an additional response delay. All the digital output modules are available as a version with relay outputs (CO contacts, up to A). Up to two modules of this type can be connected to one SENTRON 3WL5. Analog output module Digital input modules With the digital input module, up to 6 additional binary signals ( V DC) in the circuit breaker environment can be connected to the system. It is thus possible to send messages concerning the state of a switch disconnector or a control cabinet door to the ROFIBUS D or MODBUS. One module each of this type can be used for holding the si items of digital information and for automatically switching over the parameters. Digital output module with rotary coding switch Digital output modules, configurable The configurable output module is available for higher-performance solutions. With this module, random events on the CubicleBUS can be switched directly to one of si available outputs or three of these outputs can be assigned with up to si events. In other words, up to si events can be placed on one physical output with OR operation. Either BDA/BDA lus or Switch ES ower is used for configuring. A relay variant is also available here the same as for the output modules with rotary coding switch. Only one module of this type is possible per SENTRON 3WL5. Digital input module ZSI modules (short-time grading control) The use of ZSI modules is recommended when Siemens circuit breakers are arranged in several staggered levels but full grading with the smallest possible delay is to be assured nevertheless. The circuit breakers are interconnected by these modules. In case of a short-circuit, each affected circuit breaker asks the circuit breakers directly downstream whether the short-circuit has also occurred in the net, lower level. The short-circuit is eactly localized as the result, and only the net upstream circuit breaker in the energy flow direction is switched off. Digital output module, configurable Analog output modules The analog output module can be used to output the following measured values to analog indicators in the control cabinet door: I L, I L, I L3, I N or U L, U L3, U L3, U LN or L, L, L3, S tot or p.f., p.f., p.f. 3, ΔI% or f avg, U LLavg, tot, p.f. avg Four --ma/--v interfaces are available for this. The measured values to be output are selected with a rotary coding switch. By using the analog output module it is possible to do without additional converters and their conventional installation/ wiring in the main current path. Up to two modules of this type can be connected to one SENTRON 3WL5. ZSI module (short-time grading control) / Siemens LV 6 9
