Westinghouse MCP03150CR Motor Circuit Protector

The Westinghouse MCP03150CR is a 3-pole, 15 A molded-case motor circuit protector designed to deliver instantaneous magnetic short-circuit protection for three-phase motor circuits up to 600 V AC. It provides magnetic-only, instantaneous trips with an adjustable magnetic trip setting and a 65 kA interrupt rating at 480 V, featuring molded-case construction and panel-mount bolt-on or unit-mount installation for motor control centers and combination starters. As a Motor Circuit Protector, it protects industrial motor loads in control panels and automation systems across manufacturing facilities, conveyors, compressors, pumps, and HVAC equipment where fast fault interruption is critical. Common replacements include Eaton MCP03150CR, Cutler-Hammer MCP03150CR, and Allen-Bradley 140M Motor Protector, underscoring compatibility with standard industrial protection devices.
