Molded Case Circuit Breaker (MCCB) is a circuit breaker and trip device assembled in a mould case. The case functions as both an outer wrapper and to retain in proper position the breaker’s internal components. Theses cases are made from various types of electrical insulating and fire retardant plastic. MCCB can automatically cut off electric power in case of overload and short circuit. It is meant for higher rated current and is commonly used in Industrial applications.

Schneider offers the CVS, NS,Easypact series of MCCBs to cater to the growing needs of the customer and providing them with the cutting edge technologies to help circuit protection.

Compact NSX Power Circuit Breakers with integrated metering, communication capabilities & high performance levels have set new standards around the world.

Compact CVS circuit breakers are suitable for Isolation* as defined in IEC standards 60947-2 .The aim of isolation is to separate a circuit or apparatus from the remainder of a system which is energized in order the personnel may carry out work on the isolated part with complete safety. CVS MCCB locking with external pad locks* enables user to isolate and undertake maintenance with utmost safety.
