MCB - Miniature Circuit Breakers

What is Miniature Circuit Breaker or MCB?

Miniature Circuit Breaker (MCB) is used to protect an electrical circuit from short circuit and over-current. Mini Circuit Breaker basically act as a switch that automatically trips down in case of any fault or when current exceeds its maximum limit. MCBs have a rated current of about 100 ampere.

Operation of MCB Circuit Breaker

When the current exceeds its maximum limit, the movable contact of the Miniature Circuit Breaker (MCB) disconnects from the fixed contact and thereby, stopping the flow of current. In order to resume the current flow, the low voltage MCB is then manually turned ON.
