Product details

Circuit Breaker, Type TMF, 125 A, 3-Pole, 480 VAC

The ABB XT1HU3125AFF000XXX is a molded case circuit breaker (MCCB) from the XT1 family, rated 125 A continuous at 480 VAC, with a 3-pole configuration and panel-mount construction.

Panel-mount design — the breaker mounts directly to a panel via the rear mounting surface, not a DIN rail. This suits retrofit into existing switchboard cutouts or new panel builds where the breaker is bolted in place. Terminations accept copper or aluminum conductors; torque values per the nameplate label.
