Circuit breakers also known as electric breakers automatically disconnect power when a short circuit fault is detected downstream or when the circuit becomes overloaded, exceeding the electrical cable current capacity. There are three types of circuit breaker sizes on a low voltage circuit starting with the smallest Miniature Circuit Breakers (MCB) to Moulded Case Circuit Breakers (MCCB) to Air Circuit Breakers (ACB) for large switchboards.
