The HMCP250J5C is UL Listed and CSA Certified, making its certification status easy to verify when you're matching components to the requirements of an existing electrical system.

The catalog number is only one part of a proper compatibility check. Before installation, confirm the 250A amperage rating, Frame J-K size, three-pole design, 875–1750A magnetic trip range, voltage rating, terminal configuration, and physical dimensions against the equipment specifications.

Where It Works Best

The Eaton HMCP250J5C is intended for compatible motor protection applications requiring a Series C, Frame J-K, 250A motor circuit protector with a three-pole configuration. It makes particular sense for maintenance and replacement work when an existing electrical system requires a component with these specific ratings and dimensions.
