Power Circuit breakers & Switches

Explore circuit breakers, the foundation of safe power distributions and the main protection from electrically-caused fires. Protect each line carrying energy or supplying appliances by choosing the correct sized circuit breaker, that will automatically disconnect in the event of a short circuit, or a cable overload. Add switches, to enable manual on-offs or disconnection for maintenance, and transfer switches to connect backup energy sources.
