HMCP250J5 - 250Amp Motor Circuit Protector

HMCP250J5 - 250Amp Motor Circuit Protector

When you're replacing a motor circuit protector, getting the details right matters. The Eaton HMCP250J5 is a 250A, three-pole Series C motor circuit protector made for Frame J-K applications. It has an adjustable magnetic trip range of 875–1750A and is rated for a maximum of 600V AC or 250V DC. The unit uses line and load terminals and measures 10 inches high, 4.13 inches wide, and 4.06 inches deep. Those details are worth checking carefully when you're matching a replacement to existing equipment. Rather than choosing a device based on amperage alone, compare the complete HMCP250J5 catalog number, frame, trip range, voltage, pole configuration, terminals, and dimensions with the requirements of your equipment.

Material Compliance and Certifications

The HMCP250J5 is UL Listed and CSA Certified. These certifications can be important when matching a replacement component to the requirements of an existing electrical installation or facility.

Certification is only one part of the compatibility check, though. Before installation, verify the complete catalog number and ensure that the 250A rating, J-K frame, three-pole configuration, magnetic trip range, voltage ratings, terminals, and physical dimensions are appropriate for the equipment on which the device will be used.

Where It Works Best

The Eaton HMCP250J5 makes the most sense for existing motor protection equipment that calls for its particular combination of ratings: 250A, three-pole, J-K frame, Series C construction, and an 875–1750A magnetic trip range. That makes it especially relevant for industrial electrical maintenance and replacement work where maintaining the correct form, fit, and function is essential.
