HMCP250K5 - 250Amp Motor Circuit Protector

HMCP250K5 - 250Amp Motor Circuit Protector

When you're replacing a motor circuit protector, the catalog number is only part of the story. The amperage, frame, trip range, voltage, pole count, and physical fit all need to line up with the application. The Eaton HMCP250K5 is a 250A, three-pole Series C motor circuit protector made for compatible Frame J-K applications. It has a 1000–2000A magnetic trip range and is rated for up to 600V AC or 250V DC. Line and load terminals are provided, and the unit measures 10 inches high, 4.13 inches wide, and 4.06 inches deep.

Material Compliance and Certifications

The HMCP250K5 is UL Listed and CSA Certified. These certifications provide an important reference point when you're matching a replacement component to equipment or an application with specific certification requirements.

Compatibility still needs to be checked carefully. A 250A rating by itself doesn't establish that two motor circuit protectors are interchangeable. Frame size, magnetic trip range, voltage, number of poles, terminals, dimensions, and equipment requirements should all be considered before installation.

Where It Works Best

The Eaton HMCP250K5 makes the most sense in compatible motor protection equipment calling for a 250A, three-pole, Frame J-K Series C motor circuit protector with a 1000–2000A magnetic trip range.

It's particularly relevant when maintaining existing or legacy equipment, where matching the original component's specifications is critical. Instead of choosing a replacement based on amperage alone, compare the complete catalog number and ratings with those of the existing unit and its equipment documentation. When the application calls for the HMCP250K5 configuration, this unit provides the corresponding form, fit, electrical ratings, and certifications without adding claims the specifications don't support.
