Schneider Electric LE36400LSG Circuit Breaker

Square D by Schneider Electric LE36400LSG is a 400 A, 3-pole molded-case circuit breaker designed for 600 V AC service. This unit uses a Micrologic Series B trip unit with LSIG protection, delivering long-time, short-time, instantaneous, and ground-fault protection to guard feeders and distribution panels from overloads and faults. Built as part of the LE frame family, the device relies on a thermal-magnetic trip mechanism to interrupt fault currents and protect connected equipment. Suitable for industrial and large commercial electrical distributions, the LE36400LSG provides robust protection, reliable interrupting performance, and precise coordination in applications such as motor feeders, main distribution panels, and other high-current circuits in Square D LE-compatible enclosures and switchgear. With its 3-pole construction, 600 V rating, and LSIG functionality, it supports dependable protection for multi-phase systems while aligning with common Square D MCCB installation practices.
