Westinghouse MCP03150R Trip Circuit Breaker 3 Pole

Description:

The Westinghouse MCP03150R Trip Circuit Breaker is a molded case motor circuit protector designed to provide short-circuit protection for three-phase motors and industrial power distribution systems. Commonly installed in motor control centers (MCCs), industrial control panels, and machinery requiring reliable motor protection up to 600 VAC. Maintenance teams, OEMs, and plant operators use this circuit breaker for replacement, retrofit, and new installations to protect motors and associated equipment from damaging fault currents.

Applications:

The Westinghouse MCP03150R is used to provide instantaneous magnetic trip protection for AC motors and branch circuits in industrial environments. It is commonly found in manufacturing facilities, processing plants, HVAC systems, pumps, compressors, and conveyor systems where fast short-circuit interruption is critical for equipment protection. The MCP series later became part of the Eaton/Cutler-Hammer product family and remains widely available as a legacy replacement component.
