A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current from an overload or short circuit. Its basic function is to interrupt current flow after a fault is detected.

The magnetic portion of the breaker consists of an iron core with a wire coil around it, forming an electromagnet. Load current passes through the electromagnet coils so the electromagnet responds to short-circuit currents.
