Material Compliance and Certifications

The Eaton HMCPE100R3C is UL Listed and CSA Certified. Its terminals use non-aluminum material. For compliance requirements beyond these stated certifications, the manufacturer recommends contacting Eaton directly.

Certification is only one part of choosing the correct electrical component. Always confirm the breaker specifications, equipment requirements, and applicable electrical codes before installation.

Where It Works Best

The HMCPE100R3C makes the most sense in motor protection applications that specifically require a 100A, three-pole, Frame J-K Series G motor circuit protector with a T98 trip type and 300–1000A magnetic trip range.

It is particularly relevant for maintenance and replacement work where the existing equipment needs to retain the correct form, fit, and function. That means checking more than the 100A rating. Frame size, voltage, number of poles, magnetic trip range, physical dimensions, and terminal requirements all matter.
