    LITTELFUSE - 814020 Circuit Breakers.

    A circuit breaker is an automatically operated electrical device designed to protect an electrical circuit from damage caused by overload or short circuit. Unlike a fuse, a circuit breaker can be reset (either manually or automatically) to resume normal operation. Automatic units are cycling and continuously self resetting, while the manual units are used where investigation of the fault is required prior to the circuit being reset.

    Push Button Manual Reset (type III) with 90° bracket

    24V 20 Amp.

    Operating temperature: -23°C to 65°C.

    Case: metal housing/shielding small 2-screw terminals.
