Schneider Electric MAL36500 Molded Case Circuit Breaker

The MAL36500 Molded Case Circuit Breaker from Schneider Electric (Square D) is a 500 A, 3-pole device designed for 600 V AC systems. This molded-case circuit breaker provides reliable overcurrent protection for three-phase feeders and distribution circuits in industrial and commercial panels. With a 500 A rating, it is suitable for protecting substantial distribution runs while enabling selective tripping and coordinated protection within a panelboard. As part of Schneider Electric's Square D MCCB lineup, the MAL36500 is designed for use in standard low-voltage panels and accessories used in power-distribution installations. The 3-pole design indicates three-phase operation, making it appropriate for motors and multi-phase equipment in facilities that require interrupt capability for 600 V mains. Catalog designation MAL36500 identifies this specific model among Schneider Electric's molded-case breakers, providing consistent performance within the Square D protection system. Three‑pole operation supports protection of three‑phase loads, common in motors and industrial equipment, while the 600 V rating aligns with standard industrial power distribution. In typical electrical distribution layouts, these MCCBs protect feeders and branch circuits, helping to prevent damage from overloads and short circuits while enabling safe isolation and maintenance of energized systems.
