Westinghouse Electric Corporation HMCP003ADC Circuit Breaker

The Westinghouse HMCP003ADC is a three-pole molded‑case circuit breaker that provides magnetic‑only short‑circuit protection for low‑amperage three‑phase motor circuits. It is rated at 3 A with 600 V AC and 250 V DC voltage ratings, and it uses magnetic trip to interrupt faults quickly in motor protection systems. Commonly installed in motor control centers and industrial panels, it sees use across conveyors, manufacturing equipment, HVAC control systems, industrial motor starters, and automated machinery where reliable three‑phase motor protection is required. This panel-mounted device belongs to the HMCP frame family and is compatible with replacements such as Eaton HMCP003ADC, Cutler-Hammer HMCP003ADC, and Westinghouse HMCP250R3C.
