SIEMENS 3WLAir Circuit Breakers
The SENTRON 3WL circuit breaker takes into account the increased demands made on air circuit breakers in terms of operator control and monitoring of networks. With it’s great flexibility it can be used as an incoming-feeder, distribution, tie, and outgoing-feeder circuit breakers in electrical installations or for switching and protecting motors, capacitors, generators,transformers, busbars and cables.
It is easy to use and universally communication-capable. Connected to an electronic control system, it offers comprehensive possibilities for monitoring of network events.
