HMCP250G5C - 250Amp Motor Circuit Protector

HMCP250G5C - 250Amp Motor Circuit Protector

When you're replacing a motor circuit protector in existing equipment, getting the details right matters. The Eaton HMCP250G5C is a 250A, three-pole Series C motor circuit protector made for Frame J-K applications. It has a 750–1500A magnetic trip range and a maximum voltage rating of 600V AC or 250V DC. Line and load terminals are included, with non-aluminum terminal material. The unit measures 10 inches high, 4.13 inches wide, and 4.06 inches deep, providing maintenance teams and electricians with clear dimensions for comparison with the existing installation.

Material Compliance and Certifications

The HMCP250G5C is UL Listed and CSA Certified. For other compliance requirements, Eaton directs users to contact the manufacturer.

Certification is important, but it's only one piece of a correct replacement. Before installation, compare the full catalog number and electrical specifications with those of the component being replaced and the equipment requirements.

Where It Works Best

The Eaton HMCP250G5C makes the most sense in existing motor protection applications that specifically call for a 250A, three-pole Series C motor circuit protector in a J-K frame. It's particularly relevant for maintenance and replacement work, where the goal is to maintain the correct form, fit, and function.

One quick caution: 250A by itself isn't enough to establish compatibility. Check the catalog number, frame size, three-pole configuration, 750–1500A magnetic trip range, voltage rating, terminals, and physical dimensions before making the match. That extra check can save a lot of trouble once you're at the installation stage.
