6 Siemens AG 9 3WL Air Circuit reakers 3WL Air Circuit reakers/non-automatic Air Circuit reakers up to 63 A (AC) General data 5 enefits Low space requirements The SENTRON 3WL devices require very little space. Size I devices (up to 6 A) fit into a 4 mm wide switchgear panel. Size III devices (up to 63 A) are the smallest of their kind and with their construction width of 74 mm fit into a 8 mm wide switchgear panel. Modular design Components like auxiliary releases, motorized operating mechanisms, electronic releases, current sensors, 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 releases Modularity is one of the main features of the new SENTRON 3WL circuit breakers. Special LCDs, ground-fault modules, rated current modules and communication modules for the electronic releases 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. 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 assigning energy to cost centers reventive maintenance reduces the risk of expansive 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 extensive, coordinated SENTRON range of devices covers all applications between 6 A and 63 A with compact 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 SENTRON 3WL circuit breakers comply with: IEC 6947-, EN IEC 6947-, EN Climate-proof according to IEC Versions with UL 489 also available, see Catalog LV 6.
