HMCP400D5C - 400Amp Motor Circuit Protector Description

HMCP400D5C - 400Amp Motor Circuit Protector

The Eaton HMCP400D5C is a 400A, three-pole motor circuit protector from the Series C line, built around a Frame K configuration. It has a 500–1000A magnetic trip range and is rated for applications up to 600V AC or 250V DC. For maintenance teams working with existing equipment, those details matter. When an installed motor circuit protector needs to be replaced, matching the frame, amperage, pole configuration, voltage rating, trip range, and physical size can be just as important as matching the catalog number itself. If your equipment calls for this specific Series C configuration, the HMCP400D5C offers the familiar form, fit, and function needed to keep compatible equipment in service. It's a straightforward, purpose-built component that's built to last.

Key Features and Benefits

  • 400A rating: Designed for equipment requiring a 400-amp motor circuit protector.
  • Three-pole design: Matches compatible three-pole motor control applications.
  • 500–1000A magnetic trip range: An important specification to confirm when matching an existing protector.
  • Frame K: Makes it easier to check the required physical configuration and fit.
  • Series C: Designed for use with compatible Eaton Series C equipment.
  • Rated up to 600V AC and 250V DC: Clearly defined voltage limits make application matching more straightforward.
  • Line and load terminals: Uses the terminal arrangement specified for the HMCP400D5C.

Where It Works Best

The HMCP400D5C 400A motor circuit protector makes the most sense in existing motor control equipment that requires its specific Series C, Frame K, three-pole configuration. It's particularly useful in maintenance and replacement situations where the goal is simple: find a component with the correct form, fit, ratings, and intended function without introducing unnecessary changes to the existing setup.
