HMCP250K5C - 250Amp Motor Circuit Protector

HMCP250K5C - 250Amp Motor Circuit Protector

When you’re replacing a motor circuit protector in existing equipment, the details matter. The Eaton HMCP250K5C is a 250-amp, three-pole motor circuit protector from Eaton’s Series C family, designed for Frame J-K applications. It has a 1000–2000A magnetic trip range and is rated for a maximum of 600V AC or 250V DC. Line and load terminals are included, with non-aluminum terminal material. Just as important for replacement work, the HMCP250K5C has clearly defined dimensions—10 inches high, 4.13 inches wide, and 4.06 inches deep—making it easier to compare against the part already installed in your equipment.

Key Features and Benefits

• 250A rating for compatible motor protection applications
• Three-pole design for equipment requiring this pole configuration
• Frame J-K construction for the specified Series C application
• 1000–2000A magnetic trip range
• Rated for up to 600V AC and 250V DC
• Line and load terminals with non-aluminum terminal material
• Published dimensions make it easier to check physical fit before installation
• Well suited to replacement applications where the existing equipment specifies the HMCP250K5C and matching electrical characteristics

Material Compliance and Certifications

The HMCP250K5C is UL Listed and CSA Certified. For additional compliance requirements beyond the certifications provided for this model, Eaton specifies contacting the manufacturer.

As with any motor circuit protection component, compatibility shouldn't be determined by amperage alone. Check the catalog number, frame size, pole configuration, voltage rating, magnetic trip range, terminal arrangement, and physical dimensions against the requirements of the existing equipment before installation.

Where It Works Best

The Eaton HMCP250K5C makes the most sense in existing electrical equipment that specifically requires a 250A, three-pole, Frame J-K Series C motor circuit protector with a 1000–2000A magnetic trip range. It's particularly relevant for maintenance and replacement projects where keeping the correct physical fit and specified electrical characteristics is the priority.

For anyone replacing an existing unit, start with the catalog number and then confirm the ratings. If the application calls for HMCP250K5C, verify the 250A rating, three-pole configuration, Frame J-K size, voltage limits, magnetic trip range, terminals, and dimensions. That straightforward approach helps ensure you're matching the component to the equipment rather than making assumptions based on appearance or amperage alone.
