HMCP400W5 - 400Amp Motor Circuit Protector

HMCP400W5 - 400Amp Motor Circuit Protector

When you’re replacing a motor circuit protector, matching the existing equipment matters. The Eaton HMCP400W5 is a 400 amp, three-pole motor circuit protector from Eaton’s Series C line, built around a K-frame configuration. It has a 1250–2500 amp magnetic trip range and is rated for applications up to 600V AC or 250V DC. For maintenance teams and electricians working with compatible motor control equipment, those details make it easier to determine whether the HMCP400W5 is the right match for the component already in place.

Material Compliance and Certifications

The Eaton HMCP400W5 is UL Listed and CSA Certified. These certifications are useful for maintaining equipment that requires components with recognized electrical safety listings.

For replacement applications, check the complete set of specifications rather than relying on the 400A rating alone. In particular, confirm the HMCP400W5 catalog number, K-frame configuration, three-pole design, 1250–2500A magnetic trip range, voltage rating, and terminal arrangement against the existing equipment.

Where It Works Best

The HMCP400W5 motor circuit protector is best suited to applications where its specific ratings and configuration match the equipment already in service, including:

• Compatible Eaton Series C equipment
• Motor circuits requiring a 400A motor circuit protector
• Equipment designed for a K-frame device
• Three-phase applications requiring a three-pole configuration
• Applications calling for a 1250–2500A magnetic trip range
• Systems operating within the 600V AC or 250V DC maximum rating
• Commercial and industrial motor control equipment
• Maintenance and replacement projects where matching the existing component is important
