MCCB

What is MCCB?

An MCCB (Molded Case Circuit Breaker) is a protective electrical device used to safeguard circuits from overloads, short circuits, and other abnormal conditions. It offers adjustable trip settings, allowing it to handle higher current ratings compared to an MCB. When a fault occurs, the MCCB quickly disconnects the power to prevent equipment damage, fire risks, and electrical failures.


MCCBs are more reliable in terms of electrical safety than MCBs as they can be adjusted to the electrical load of a facility. Users can adjust their trip to be sensitive to the higher current ratings of a zone. These devices are most commonly used in large spaces with heavy electrical loads like commercial buildings, industrial plants, and heavy-duty machinery.
