Westinghouse Electric HMCP400K5C Circuit Breaker

The Westinghouse HMCP400K5C Circuit Breaker delivers magnetic-only short-circuit protection for high-amperage three-phase motor circuits in industrial power systems. This 3-pole, 400 Amp device is rated for 600 Volt AC and is designed for bolt-on panel mounting in motor control centers and industrial panels, enabling rapid fault interruption to safeguard motors, drives, and associated equipment. Common applications include conveyors, manufacturing equipment, pumps, compressors, HVAC control systems, and automated machinery, with industrial motor starters and other high-current loads benefiting from dependable protection. The HMCP series is designed for motor protection and automation control applications, and its magnetic-only trip type ensures operation in fault conditions without relying on thermal elements. Common replacements include Eaton HMCP400K5C, Cutler-Hammer HMCP400K5C, and Westinghouse HMCP250W5.
