HMCP400J5C - 400Amp Motor Circuit Protector Description

HMCP400J5C - 400Amp Motor Circuit Protector

When you need an Eaton HMCP400J5C for an existing application, getting the details right matters. This 400A, three-pole Series C motor circuit protector is designed for Frame J-K applications and has an 875–1750A magnetic trip range. It is rated for a maximum of 600V AC or 250V DC and comes with line and load terminals made of non-aluminum material. For maintenance and replacement work, those specifications make it easier to compare the HMCP400J5C with the device already installed and to confirm that the electrical and physical requirements align.

Key Features and Benefits

  • 400A rating: Designed for applications requiring a 400-amp motor circuit protector.
  • Three-pole construction: Matches equipment requiring a three-pole configuration.
  • 875–1750A magnetic trip range: An important specification when confirming the correct device for an existing system.
  • Frame J-K: Built for applications designed around this frame size.
  • Series C: Part of Eaton's Series C product family.
  • Voltage ratings: up to 600V AC and 250V DC.
  • Line and load terminals: Uses non-aluminum terminal material.

Material Compliance and Certifications

The HMCP400J5C is UL Listed and CSA Certified. These certifications can be important when replacing electrical components in equipment where the original specifications and certification requirements need to be maintained.

Eaton lists additional compliance information as “Contact Manufacturer.” Installation requirements should always be checked against the equipment documentation and applicable electrical standards.

Where It Works Best

The HMCP400J5C makes the most sense in existing motor protection equipment that calls for a 400A, three-pole, Frame J-K Series C motor circuit protector with an 875–1750A magnetic trip range. It is especially useful in maintenance and replacement situations where matching the original component's electrical ratings, physical dimensions, and configuration is the priority.

Before using the HMCP400J5C as a replacement, compare more than the amperage rating. Check the catalog number, frame size, number of poles, magnetic trip range, voltage rating, terminal configuration, and dimensions against the existing device and equipment documentation. That simple check can go a long way toward confirming the right form, fit, and function for the application.
