Narva 54750BL 50A Automatic Reset Straight Bracket Circuit Breaker

Narva's Circuit Breaker 50A Auto Reset is an automatically operated electrical device designed to protect an electrical circuit from damage caused by overload or short circuit. Unlike a fuse, which operates once and then has to be replaced, a circuit breaker can be reset (either manually or automatically) to resume normal operation. Automatic units are cycling and continuously self resetting, whilst the manual units are used where investigation of the fault is required prior to the circuit being reset.
