Westinghouse Electric MCP0322 Molded Case Circuit Breaker

The Westinghouse MCP0322 is a 3-pole molded case circuit breaker rated for 3 A at 600 VAC, with a magnetic trip, built for motor-circuit protection in industrial power distribution and control panels. This panel-mount device uses screw terminal connections and supports three-phase, 50/60 Hz operation for rapid fault isolation in motor-driven equipment. Common applications include motor control centers, industrial machinery, conveyors, HVAC systems, pump controls, packaging machinery, and process-control assemblies that require dependable three-phase protection in factory automation environments. It carries an industrial-duty rating and is designed to protect low-amperage circuits from short circuits and electrical faults. Compatible installations include motor control centers and industrial panels, where it serves as motor circuit protection in OEM electrical assemblies. Common replacements include Eaton HMCP003A0C, Allen-Bradley 140M-C2E-B03, and Square D FA34003.
