The ABB XT4HU3250DFF000XXX is a 3-pole molded case circuit breaker from the XT4H-D series, rated 25 A continuous at 600 VAC. Panel-mount form factor bolts into a switchboard or distribution panel; no DIN-rail adapter here.
This part carries a current lifecycle stage, meaning it remains in ABB's active catalog for new installations and replacements. No last-time-buy or phase-out notice is on record.
Panel-mount design requires a cutout and bolt-down — no DIN-rail clip. The 3-pole block handles three-phase loads; the 25 A frame suits motor branch circuits, feeder protection, or distribution sub-feeders up to that continuous rating. 600 VAC rating covers 480 V and 600 V systems with headroom.
