Answer:

During Short Circuit, the sudden and dramatic rise of electric current causes electro-mechanical displacement of the plunger (4) from the tripping coil or solenoid (2). The plunger strikes the trip lever causing the immediate release of the latch mechanism, opens the contacts and thus breaks the circuit.

Explanation:

Whenever continuous overcurrent flows through MCB, the bimetallic strip is heated and deflects by bending. ... As this mechanical latch is attached with the operating mechanism, it causes to open the miniature circuit breaker contacts, and the MCB turns off thereby stopping the current to flow in the circuit.
