Siemens AG 203 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 air 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: Conductor cross-sections 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 Applications 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 air circuit breakers comply with: IEC 60947-2 Climate-proof according to IEC 60068-2-30. Versions with UL 489 also available, see Catalog LV 6. For further standards, see Appendix.
