Overview
The Cutler-Hammer HMCP015B0 is a Series C molded-case motor circuit protector engineered for industrial motor control and short-circuit protection. Part of Eaton’s established HMCP family, this 3-pole unit delivers instantaneous magnetic-only trip response at 15A rated current and operates up to 600VAC or 250VDC. The HMCP015B0 is commonly integrated into combination starters and motor control centers where precise short-circuit coordination is required alongside external overload relays.
Key Features
- 3-Pole Configuration: Supports 3-phase motor control applications.
- Instantaneous Magnetic Trip: Provides immediate response to short-circuit events without thermal delay.
- Adjustable Trip Range: Magnetic setting range of 45–150 amps for coordination with external overload devices.
