A circuit breaker is an electrical safety device designed to protect an electrical circuit from damage caused by overcurrent. Its basic function is to interrupt current flow to protect equipment and to prevent the risk of fire. 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. WebA fuse melts to break the circuit if the current is too large. Some components are used to respond to some physical change in our surroundings, eg temperature rise (or fall), light level change ...
