Molded Case Circuit Breakers

Molded Case Circuit Breakers
MCCBs are industrial-grade circuit protectors that offer thermal and magnetic protection with high interrupt ratings up to 100kA. These circuit breakers are fully-enclosed and able to be independently installed with the need for a panel board. MCCB feature fixed and adjustable trip unit options, can be reset manually after tripping, and do not require immediate replacement.
