Circuit breaker, an electrical protective device which is designed to detect a change in current between circuit wires and interrupt the circuit and stop the electricity flow.
Explanation
A circuit breaker works similar to fuse.
It will detect the difference in the quantity of flow of current.
If there is a vast variation in the current or voltage like occurring due to high voltage or short circuit, the contacts of circuit breaker will open leading to block the current flow.
The current flow will be block by the mechanical force produced by spring or any other kind of thermal or magnetic prohibition in the breaker unit.
