Circuit Breakers AC-DC-Fuse

Circuit Breaker CB is an electrical safety device designed to protect an electric circuit from damage caused by overcurrent Its basic function is to interrupt current flow to protect equipment and to prevent the risk of fire.

DC CB is used for Direct Current in a Solar System.

AC CB is used in an Electric System with Alternating Current.

Unlike a Fuse, which operates once and then must be replaced, a circuit breaker can be reset (either manually or automatically) to resume normal operation.
