Molded Case Circuit Breakers - MCCBs

Schneider Electric India’s ranges of Molded Case Circuit Breaker devices for industrial applications provide unique and customised solutions depending on different load requirements. The different ranges of MCCB’s are among the most sophisticated industrial circuit breakers available in the country.

What is MCCB?

MCCB is a short form for Molded Case Circuit Breaker.. It is a common example of an electrical safety device that is more often than not used when the load current is significantly higher than the limit of a miniature circuit breaker.

The MCCB offers protection against short circuit faults and is even used for switching the circuits. It can be employed for higher current ratings as well as fault level, in the case of a few domestic purposes. The wide current ratings and high breaking capacity in Molded Case Circuit Breaker mean that they are even suitable for industrial reasons.

Here are some features of MCCBs:

1. The tripping circuit of an Molded Case Circuit Breaker is moveable
2. The MCCB has single, two, three, or four-pole versions
3. The rating current of an MCCB is 10 to 200 amps (the rating current is the maximum current that the circuit should draw)
4. MCCB’s are primarily used in heavy current circuits
5. They are commonly used in heavy-duty industrial applications
