HMCP400K5 - 400Amp Motor Circuit Protector

HMCP400K5 - 400Amp Motor Circuit Protector

When your existing motor protection application calls for an Eaton HMCP400K5, getting the specifications right matters. This 400A, three-pole Series C motor circuit protector is built for Frame J-K applications and has a 1000–2000A magnetic trip range. It is rated for a maximum of 600V AC and 250V DC and comes with line and load terminals. For maintenance teams, electricians, and facilities working with existing equipment, the HMCP400K5 provides a straightforward option when the application requires this particular combination of frame size, amperage, pole configuration, voltage, and trip range.

Material Compliance and Certifications

The HMCP400K5 is UL Listed and CSA Certified. Eaton lists additional compliance information as “Contact Manufacturer.”

For replacement applications, certifications are only one part of the compatibility check. The catalog number and the electrical, mechanical, and application specifications should also be compared with those of the existing equipment and its documentation.

Where It Works Best

The Eaton HMCP400K5 makes the most sense in existing motor protection equipment that specifically requires a 400A, three-pole Series C motor circuit protector in a J-K frame, along with a 1000–2000A magnetic trip range. That makes it particularly relevant for maintenance, repair, and form-fit-function replacement work involving compatible legacy or installed systems.

Before using the HMCP400K5 as a replacement, check more than the amperage stamped on the existing device. Frame size, number of poles, voltage rating, magnetic trip range, terminal configuration, physical dimensions, and catalog number all matter. Matching those details is the practical way to determine whether this is the right component for the equipment.
