Features Coordinated communication concept using the PROFIBUS DP or MODBUS, ranging from 6 A to 6300 A with 3VL molded case circuit breakers and 3WL air circuit breakers The high level of modularity of circuit breakers and accessories allows easy retrofitting of all communication components Significant additional benefits for the switchgear due to the possibility of linking up external input and output modules to the circuit breaker-internal CubicleBUS of the 3WL Innovative software products for parameterization, operation, monitoring, and diagnostics of circuit breakers, both locally or via PROFIBUS DP, MODBUS or Ethernet/Intranet/Internet Complete integration of the circuit breakers into the Totally Integrated Power and Totally Integrated Automation solutions Communication: For air circuit breakers with optional communication function (ETU45B or ETU76B Electronic Trip Unit) see pages /9 to /36. For accessories see pages /59 and /60. For more information see also chapters "Measuring Devices and Power Monitoring" and "Software". Siemens LV /7
8 Siemens AG 204 3WL /Non-Automatic up to 6300 A (AC), IEC Introduction Benefits Low space requirements The 3WL air circuit breakers require very little space. I devices (up to 2000 A) fit into a 400 mm wide switchgear panel. III devices (up to 6300 A) are the smallest of their kind and with their construction width of 704 mm fit into an 800 mm wide switchgear panel. Modular design Components like auxiliary releases, motorized operating mechanisms, Electronic Trip Units, current transformers, auxiliary circuit signaling switches, automatic reset devices, interlocks and engagement operating mechanisms can all be exchanged or retrofitted at a later stage, thus allowing the circuit breaker to be adapted to new, changing requirements. The main contact elements can all be replaced in order to increase the endurance of the circuit breaker. Retrofittable modules for Electronic Trip Units Modularity is one of the main features of the new 3WL circuit breakers. Special LCDs, ground-fault modules, rating plugs and communication modules for the Electronic Trip Units are available for fast and easy retrofitting and adaptation to changing requirements. Communication/measurement functions 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: Fast and reliable parameterization 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 allocating energy to cost centers Preventive maintenance reduces the risk of expensive plant downtimes Measurement function with a very wide range of measured values, such as current, voltage, energy, power etc. Can be used in 000 V AC and 690 V IT networks 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. When connected to an electronic I&C system, the air circuit breakers offer a wide range of options for monitoring network events. The extensive, coordinated SENTRON range of devices covers applications between 6 A and 6300 A with molded case and air circuit breakers. The AC devices are available as circuit breakers and non-automatic air circuit breakers. DC devices are only available as nonautomatic air circuit breakers. Standards 3WL circuit breakers comply with: IEC IEC Annex F / CISPR /22 Class B Climate-proof according to IEC Versions with UL 489 also available, see Catalog LV 6.
