It protect the circuit in abnormal condition by tripping as well as a switch.

Circuit breaker is protective device which protect electric component at abnormal condition.

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.

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

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 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

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.
