HMCP250D5 - 250Amp Motor Circuit Protector

HMCP250D5 - 250Amp Motor Circuit Protector

When you're replacing motor protection equipment, the details matter. The Eaton HMCP250D5 is a 250A, three-pole Series C motor circuit protector made for Frame J-K applications. It has an adjustable 500–1000A magnetic trip range and is rated for a maximum of 600V AC or 250V DC. For maintenance teams, electricians, and facility professionals working with existing equipment, the HMCP250D5 offers clearly defined specifications that make it easier to check form, fit, and functional compatibility before installation. If your existing application specifically calls for catalog number HMCP250D5, matching the catalog number along with the frame, amperage, voltage, trip range, and pole configuration is an important part of selecting the correct replacement.

Material Compliance and Certifications

The HMCP250D5 is UL Listed and CSA Certified. The manufacturer's supplied specifications direct customers to contact the manufacturer for additional compliance information.

For a replacement application, certification is only one part of the equation. It's also important to confirm the catalog number, J-K frame, 250A rating, three-pole configuration, 500–1000A magnetic trip range, voltage rating, terminal arrangement, and physical dimensions against the requirements of the equipment being serviced.

Where It Works Best

The Eaton HMCP250D5 makes the most sense in existing or legacy motor protection systems specifically designed around its ratings and configuration. That includes applications calling for a 250A, three-pole, J-K frame Series C motor circuit protector with a 500–1000A magnetic trip range.

For replacement work, don't stop at seeing "250A" on the label. Two electrical components can share an amperage rating and still have important differences. Check the complete HMCP250D5 catalog number, then confirm the frame size, number of poles, trip range, voltage, terminals, and dimensions. Those details are what help establish whether the component provides the required form, fit, and function for the existing system.
