Westinghouse MCP23480R Trip Auxiliary Breaker Unit

Westinghouse MCP23480R Trip Auxiliary Breaker is a 3-pole, 50 A magnetic-trip auxiliary circuit breaker designed for motor and branch circuit protection in industrial control environments. Commonly installed in motor control centers, manufacturing equipment, conveyor systems, and industrial automation panels, it provides short-circuit protection and remote trip indication for industrial motors and related equipment. The unit supports 600 VAC operation at 50/60 Hz with a three-phase configuration, is panel-mountable, and uses screw terminal connections, featuring a magnetic trip mechanism for fast, reliable disconnection under fault conditions. It is rated for industrial-duty service and is intended for motor control centers and industrial panels requiring reliable motor protection and auxiliary trip functionality. Typical applications include HVAC systems, pump controls, packaging machinery, process automation systems, material handling equipment, and OEM control assemblies. For retrofit or maintenance, common replacements include Eaton HMCP050K2C, Allen-Bradley 140M-C2E-B50, and Square D FA34050. This Westinghouse part, with part number MCP23480R, is a dedicated trip auxiliary circuit breaker designed to protect three-phase motors and support remote trip indication in demanding industrial environments.
