Square D MAP36600U Molded Case Circuit Breaker

The Square D MAP36600U Molded Case Circuit Breaker is a 600-amp, three-pole protective device designed for 480 VAC power distribution, belonging to Square D's MAP line of molded-case circuit breakers and intended for inclusion in industrial and commercial electrical installations where substantial current protection is required. As a molded case circuit breaker, it provides overcurrent protection for three-phase feeders inside distribution panels, enabling automatic interruption during overload or fault events to safeguard conductors, equipment, and wiring enclosures, while accommodating standard field configurations and wiring practices used in North American low-voltage systems. With its 600 A frame and three-pole configuration, the MAP36600U supports high-current, three-phase circuits and is designed to fit compatible MAP enclosures, supporting straightforward integration with other Square D protective devices in a coordinated protection scheme. In typical applications at facilities operating 480 V three-phase service, this model functions as either a main or feeder protection device within larger power-distribution architectures, aligning with Square D's ecosystem of MCCBs and enabling circuit separation, and fault isolation within larger distribution architectures.
