Which device can be reset after tripping?

Explanation:
When a fault occurs in a branch circuit, protective devices interrupt current to prevent damage. The device that is designed to be reset after it trips is the circuit breaker. After you clear the fault, you can restore power by flipping the breaker back to the ON position (or using the reset action on a modern breaker). Fuses aren’t resettable—they open the circuit by melting and must be replaced. While other devices like GFCIs or overload relays can have reset actions, the circuit breaker is the standard reusable protection device intended to be reset after tripping.
