Material Compliance and Certifications

The HMCP400R5 is UL Listed and CSA Certified, providing installers and maintenance professionals with clear certification information when verifying the requirements of an existing application.

Compatibility shouldn’t be determined by amperage alone. When replacing an existing motor circuit protector, check the complete catalog number, frame size, number of poles, magnetic trip range, voltage rating, terminal arrangement, and physical dimensions. Matching those details helps preserve the intended form, fit, and function of the equipment.

Where It Works Best

The Eaton HMCP400R5 makes the most sense in motor protection equipment specifically designed for a 400A, three-pole, Series C Frame J-K motor circuit protector with a 1750–3500A magnetic trip range. It’s particularly relevant when maintaining existing or legacy electrical equipment and the job calls for matching the characteristics of the component already in service.
