An MCB is an automatic switch designed to open an electrical circuit in the event of a short circuit or overload. When the supply current rises above safe limits, a bimetallic strip inside the device heats up, bends and trips the circuit breaker. Since higher spikes cause the strip to heat up more quickly, the MCB activates more quickly in response to large power surges.
