Information About HMCP400X5W
The HMCP400X5W is a molded case motor circuit protector from Eaton’s Series C product family, developed specifically for protecting motor branch circuits from short-circuit faults. Unlike thermal-magnetic breakers, this device uses a magnetic-only trip mechanism to coordinate with external overload relays in motor control systems. It is designed for J-K frame configurations and is commonly installed in motor control centers, industrial machinery panels, and automation equipment. The unit supports operation up to 600 V AC or 250 V DC and features a magnetic trip range of 2000–4000 A for reliable short-circuit protection.
Key Features:
- Magnetic-Only Motor Protection: Provides rapid short-circuit protection while allowing coordination with external overload relays.
- 400 Amp Current Rating: Designed for protecting large industrial motor branch circuits.
- Adjustable Magnetic Trip Range: Trip range of 2000–4000 A enables coordination with motor starting characteristics.
- Series C Compatibility: Built for Eaton Series C J-K frame motor protection systems.
- Three-Pole Configuration: Supports protection of three-phase industrial motor circuits.
- High Voltage Capability: Rated for operation up to 600 V AC and 250 V DC.
- Industrial Motor Control Use: Commonly installed in motor control centers and heavy equipment panels.
- Terminal-Free Configuration: Supplied without terminals for flexible installation in specialized assemblies.
The HMCP400X5W delivers the reliability and precision required for protecting industrial motor circuits from short-circuit faults.
