Overview
The Westinghouse HMCP015E0C motor circuit protector is a magnetic-only molded case breaker designed for motor circuit protection in industrial and commercial environments. Operating at ratings of 15A, 3-pole, 600VAC/250VDC, this F-Frame device provides instantaneous magnetic trip protection to interrupt short circuits and phase faults in motor starter applications.
Key Features
- Magnetic Trip Only: Instantaneous overcurrent protection without thermal overload capability; overload protection must be achieved through motor starter heater elements.
- Molded Case Design: Compact, durable construction with non-aluminum line and load side lug terminals for secure panel mounting.
- F-Frame Configuration: Fits standard mounting in motor control enclosures and combination starter panels.
- Adjustable Trip Range: Magnetic setting 45–150A with multiple cam settings to match motor full-load current from 3.4–12.6A.
- Industry Certifications: UL listed and CSA certified for compliance with electrical safety standards.

- Soft-start and VFD motor protection circuits
- Industrial manufacturing facilities and production lines
- Commercial HVAC and pump systems requiring motor branch circuit protection
- Machine tool and automation equipment control panels
Compatibility & Replacements
Compatible With
- Eaton Cutler-Hammer motor control combination starters
- Freedom 2100 series motor control centers
- Standard molded case circuit breaker enclosures and panels
- Motor starters with heater overload elements (NEMA Size 0)
- 3-phase motor circuits rated 3.4–12.6A full load amperes
Replaces / Drop-In Replacement For
The HMCP015E0C directly replaces other Westinghouse, Eaton, and Cutler-Hammer HMCP015E0C units. Verify part compatibility with your system integrator or panel builder before ordering, as magnetic trip settings must match your motor’s full-load amperage profile.
Works With
- Motor starter thermal overload relays and heater elements
- Standard 3-phase AC motor circuits
- Control relay logic and programmable logic controllers (PLCs) monitoring trip status
- Soft starters and variable frequency drives requiring branch circuit protection
