Westinghouse HMCP007C0 Motor Circuit Protector

Westinghouse HMCP007C0C is a 3-pole motor circuit protector designed for 600 V AC service with a 7 A nominal current rating, part of Eaton Cutler-Hammer’s Series C HMCP family in the F-frame and configured for magnetic, instantaneous protection in motor circuits. This feed-through device provides line and load terminals (non-aluminum lug construction) and a fixed, non-interchangeable magnetic trip in the 21–70 A range, delivering a 65 kA short-circuit current rating at 480 V. The physical size is approximately 5 in wide by 7.4 in deep by 4.9 in high, and the unit is UL 489, CSA C22.2, and CE certified with IEC 157-1 applicable standards. Motor sizing guidance notes a motor full-load current range of 1.5–5.7 A, aligning the HMCP007C0C with small to fractional horsepower motor protections. This molded-case circuit protector is intended for panel or MCC installations where a magnetic-only trip function is required, providing reliable overcurrent protection for motors while maintaining a compact, robust form factor.
