Circuit breaker is a protective equipment, that break the supply during abnormal condition. ie; Over current, earth fault,over voltage, under voltage,under frequency etc., its depends upon what protective relay we have installed.
The CB having Shunt coil-for remote tripping, Open & closing coil

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

It is just a switch. Relay is different component which gives command to the circuit breaker during abnormal conditions, don't be confused that circuit breaker protects the system its the combination of relay and breaker which protects the system.

The Circuit breaker is switching device which turns the electrical circuit on or off according to operation command C. B never response for on command when there is any fault in circuit switch can response so in my hand the correct answer is C.

For your kind information Circuit Breaker will trip only when sudden greater change in current/voltage value,not at overload condition. For over load protection OLR (Over Load Release coil) is used.

Circuit breaker break the circuit when it sense any abnormal condition in the circuit using relay. Relay is a very important component in a circuit breaker.

Its an electronic device which opens its contact when the relay detects which fault in the circuit by sending trip signal to circuit breaker.

@Rakesh.
They are asking for a circuit breaker, they are not asking if it can be reset.
I think the right answer is a fuse.
