Schneider Electric MAL36400 Molded Case Circuit Breaker

Schneider Electric's Square D MAL36400 Molded Case Circuit Breaker is a 400 A, 3‑pole MCCB rated for 600 V, designed to protect feeders and bus sections within commercial and industrial electrical distributions. It belongs to the MAL family of molded‑case breakers and supports feed‑through wiring with line and load lugs, enabling straightforward field installation in compatible panels. The device uses thermal‑magnetic tripping to provide both overload and short‑circuit protection. In catalog listings, MAL36400 is specified with an interrupting capacity of 30 kA at 480 V, aligning with its use in systems where fault currents at those voltages are possible. The MAL36400 is marketed by Square D/Schneider Electric as a 400 A, 3P, 600 V molded case circuit breaker, suitable for main‑and feeder‑protection applications within Schneider Electric distribution gear.
