What is MCB?

Miniature Circuit Breaker (MCB) is a type of circuit breaker that is small in size. It immediately cuts off the electrical circuit during any unhealthy condition in the electricity supply systems, such as an overcharge or a short-circuit current. Although a user may reset the MCB, the fuse may detect these situations, and the user must replace it.

When an MCB is subject to continuous over-current, the bimetallic strip heats up and bends. An electromechanical latch is released when the MCB deflects the bi-metallic strip. When the user connects this electromechanical clasp to the working mechanism, it opens the microcircuit breaker contacts. Consequently, it causes the MCB to switch off and terminate the current flowing. The user should individually switch on the MCB to restore the current flow. This device guard against defects caused by excessive current, overload, and short circuits.
