Schneider Electric MGL36300 Molded Case Circuit Breaker

Schneider Electric's PowerPact M-Frame molded case circuit breaker, model MGL36300, is a three-pole, 300-amp MCCB rated for 600 V AC in industrial and commercial power-distribution environments. It employs an electronic trip unit (ET 1.0) and delivers an 18 kA short-circuit interruption capacity at 600 VAC, enabling rapid fault clearance in distribution panels and switchgear assemblies. Termination is via lug connections, compatible with PowerPact enclosures and the M-Frame family, for straightforward field wiring, mounting flexibility, and reliable integration with Schneider Electric protection schemes. The MGL36300 sits within the PowerPact M lineup, a series of molded-case breakers designed to protect feeders and equipment across medium- and large-scale industrial and commercial electrical distributions. This configuration supports medium-current protection needs in electrical distribution systems and aligns with Schneider Electric's approach to coordinated protection using PowerPact components.
