Overview
The Eaton HMCP070M2C motor circuit protector is molded case, 3-pole, Series C device engineered for short-circuit protection in motor circuits. Rated at 70 amperes, 600V AC / 250V DC, this protector features a magnetic instantaneous trip mechanism with adjustable range from 210 to 700 amperes. Frame size J-K accommodates NEMA Starter Size 2 motors with full-load current ratings from 16.1 to 59.1 amperes. Non-aluminum terminals ensure superior corrosion resistance and long service life in demanding industrial environments.
Key Features
- Magnetic Trip Only—instantaneous short-circuit protection without thermal overload elements (separate motor starter overload protection required)
- Adjustable Trip Range—210–700A selectable via cam dial, covering multiple motor sizes in a single frame
- Compact J-K Frame—saves panel space while delivering robust protection
- Non-Aluminum Terminals—superior reliability and corrosion resistance for long-term performance
