Material Compliance and Certifications

The HMCP400X5 is UL Listed and CSA Certified. Those certifications can be important when you're matching a replacement component to the requirements of an existing electrical system.

For applications with additional material-compliance requirements, check the applicable manufacturer documentation for the specific installation. Compatibility should always be determined by the complete set of electrical and physical specifications rather than by the device's appearance alone.

Where It Works Best

The HMCP400X5 makes the most sense in commercial and industrial motor control applications designed around its particular specifications. That means equipment calling for a 400A, three-pole Series C motor circuit protector with a J-K frame and 2000–4000A magnetic trip range.

It can be especially useful when you're maintaining existing or legacy equipment and need to preserve the original component's form, fit, ratings, and intended function. In those situations, getting an exact match to the specification is far more important than simply finding something that looks similar.
