Compact Circuit Breaker

Miniature circuit breaker(MCB) is a small-capacity plastic case circuit breaker with very compact structure. It is a branch of low-voltage circuit breakers, and has now become a major category of terminal electrical appliancesA circuit breaker is an electrical safety device designed to protect an electrical circuit from damage caused by overcurrent.

Its basic function is to interrupt current flow after protective relays detect a fault.When the circuit is closed, which is a normal condition, the contacts touch each other and carry the current under this condition. Under a closed circuit breaker, current-carrying contacts are known as electrodes that engage each other due to the pressure of a spring.Let's start with the basics – just what is a miniature circuit breaker? An MCB is an automatically operated electrical switch. Miniature circuit breakers are intended to prevent damage to an electrical circuit as a result of excess current.
