HMCP400F5 - 400Amp Motor Circuit Protector

HMCP400F5 - 400Amp Motor Circuit Protector

When you're replacing a motor circuit protector, getting the details right matters. The Eaton HMCP400F5 is a 400A, three-pole motor circuit protector in the Series C, Frame K family. It has a 625–1250A magnetic trip range and is rated for a maximum of 600V AC or 250V DC. For maintenance teams working with existing equipment, those specifications make it easier to determine whether the HMCP400F5 matches the unit already in service.

Material Compliance and Certifications

The HMCP400F5 is UL Listed and CSA Certified, giving buyers clear certification information when matching a replacement component to existing equipment requirements.

Compatibility should always be checked against the application before installation. In particular, confirm the 400A rating, Frame K size, three-pole configuration, 625–1250A magnetic trip range, voltage ratings, terminals, and physical dimensions against the equipment documentation and the unit being replaced.

Where It Works Best

The Eaton HMCP400F5 makes the most sense in motor control applications specifically designed around its 400A Series C, Frame K configuration. It's especially useful when maintaining existing or legacy equipment and the job calls for matching the original component's electrical ratings and physical characteristics rather than changing the system configuration.

For replacement work, don't stop at the 400A rating. Check the complete set of specifications—including frame size, number of poles, magnetic trip range, maximum voltage, terminals, and dimensions. When those details line up with the existing application, the HMCP400F5 provides the form, fit, and function needed to keep the equipment configured as intended.
