Where It Works Best

The HFXD63B100 100A 3-pole circuit breaker is best suited for compatible commercial and industrial electrical distribution equipment, especially existing or legacy systems designed around the HFXD6 Sentron frame and this breaker’s particular electrical and physical characteristics.
Replacing an existing breaker? The 100A rating is important, but it’s only part of the compatibility check. Compare the HFXD63B100 part number, HFXD6 frame, three-pole configuration, system voltage, required A.I.C. rating, non-interchangeable trip unit, load-side terminal arrangement, frequency, temperature rating, reverse-feed requirements, and physical dimensions with the equipment being serviced.
