HFXD63B250 - 250Amp Circuit Breaker

HFXD63B250 - 250Amp Circuit Breaker

Need to match a HFXD63B250 circuit breaker to an existing electrical system? Start with the full specification, because amperage alone doesn’t tell the whole story. The HFXD63B250 is a 250-amp, 3-pole HFXD6 Sentron frame molded case circuit breaker designed for compatible commercial and industrial electrical distribution equipment. Physical fit is just as important when you’re working with legacy equipment, and the HFXD63B250 measures 4.50" W x 9.50"H x 4.00" D. When the HFXD6 frame, 250A rating, three-pole configuration, trip arrangement, terminal setup, dimensions, and electrical ratings line up with the equipment requirements, the HFXD63B250 can provide the intended form, fit, and function for a compatible replacement application.
