HMCP050K2 - 50Amp Motor Circuit Protector

HMCP050K2 - 50Amp Motor Circuit Protector

When you’re replacing a motor circuit protector in existing equipment, the specifications must align. The Eaton HMCP050K2 is a 50-amp, three-pole motor circuit protector from the Series C family, designed for J-K frame applications. It has a 50–500A magnetic trip range and is intended for applications that require this combination of frame size, pole configuration, amperage, and trip range.

Key Features and Benefits

• 50A rating for applications requiring this specific amperage.
• 50–500A magnetic trip range to match the specified motor protection requirements.
• Three-pole configuration for equipment designed around a three-pole protector.
• J-K frame size helps simplify identification when matching an existing component.
• Part of the Eaton Series C product family.
• Useful for form, fit, and functional replacement in compatible existing and legacy equipment.

Material Compliance and Certifications

The HMCP050K2 is UL Listed and CSA Certified. These certifications can be important when maintaining existing equipment designed around components that carry specified approvals.

For other compliance requirements, the manufacturer's supplied information states “Contact Manufacturer.” Application-specific material or regulatory requirements should therefore be verified before installation rather than assumed.

Where It Works Best

The Eaton HMCP050K2 makes the most sense in existing motor protection equipment that calls for a 50A, three-pole Series C motor circuit protector with a J-K frame and 50–500A magnetic trip range. That makes it particularly relevant for maintenance and replacement projects where keeping the original electrical and physical configuration matters.
