Molded Case Circuit Breakers

Get ready for a molded case circuit breaker (MCCB) - a circuit breaker that is assembled in a molded case. Featuring a current rating of up to 3200 A, and with adjustable trip settings, MCCBs can operate to a wide range of voltages, and frequencies of 50 Hz, 60 Hz or 400 Hz. MCCBs provide circuit overload protection, short circuit protection (short-time and instantaneous), as well as ground fault and earth-leakage protection for your electrical distribution system. Schneider Electric brings the legendary ComPact and PowerPact Multistandard MCCB series, which come in perfectly compact frame size and can cover current ratings between 16 A to 3200 A. Featuring variable trip unit options and delivering stable performance, these two MCCB ranges offer reliable protection for your electrical distribution system.
