Circuit Breakers and Switches

Check our wide range of electric circuit breakers and switches designed for routing or interrupting current in the electrical distribution circuit, automatically or manually. From the legendary Compact™ molded case circuit breaker (MCCB), to the MasterPact high-current air circuit breaker (ACB) and Miniature circuit breaker types (MCCB), our products offer reliability and performance for your electrical distribution system, providing electrical protection in the event of circuit overload or short circuit.

High Current Air Circuit Breakers

High current air circuit breakers operate in atmospheric air conditions providing overcurrent and short-circuit protection for circuits rated from 800 A to 6300 A, and are used as a feeder and coupler within the electrical distribution system. Schneider Electric MasterPact air circuit breakers integrate monitoring for energy efficiency offering maximum safety. MasterPact ACBs have been designed with easy installation and retrofitting in mind. Featuring powerful MicroLogic control units, MasterPact delivers protection and performance for your electrical distribution system.
