HMCP400A5 - 400Amp Motor Circuit Protector

HMCP400A5 - 400Amp Motor Circuit Protector

When you’re replacing a motor circuit protector, the details matter. The Eaton HMCP400A5 is a 400A, three-pole Series C motor circuit protector made for compatible J-K frame applications. It has a 350–700A magnetic trip range and is rated for a maximum of 600V AC or 250V DC. Line and load terminals are part of the configuration. For anyone maintaining existing motor control equipment, those specifications provide the key starting points for determining whether this is the correct form, fit, and functional replacement.

Material Compliance and Certifications

The HMCP400A5 is UL Listed and CSA Certified, providing installers and maintenance professionals with clear certification information when verifying the requirements of an existing application.

As with any replacement electrical component, don’t rely on amperage alone. Check the complete set of specifications against the existing equipment, including the J-K frame, three-pole configuration, 350–700A magnetic trip range, voltage rating, terminal arrangement, and physical dimensions.

Where It Works Best

The Eaton HMCP400A5 is best suited to existing motor control and electrical systems designed for a 400A, three-pole, J-K frame Series C motor circuit protector. That makes it particularly useful in maintenance and replacement situations where keeping the original form, fit, and function is important.
