A MCB (miniature circuit breaker) is a type of electrical switch designed to protect electrical circuits from overcurrents and short circuits. It is a critical safety device used in residential, commercial, and industrial electrical distribution systems.

Trip Curve: Different circuit breakers have different trip curves, which define how quickly they trip in response to overcurrents. Select a trip curve suitable for the connected load and the desired level of protection. Interrupting Capacity: The interrupting capacity indicates the maximum fault current the breaker can safely interrupt.

RCCB Breakers: RCCB stands for Residual Current Circuit Breaker. They are designed to quickly disconnect any circuit as soon as current leaks to the earthing wire.
