It is a wall-mount unit, so it lands on a backplate or enclosure wall rather than a DIN rail — factor that into your panel layout and gland-plate planning. The single-pole construction (1-pole) means this breaker switches one phase only — typical for a single-phase branch circuit or a DC application where only one ungrounded conductor needs protection. It is not a 3-pole device; if your BOM calls for three-phase switching, this is the wrong pole count.","metaTitle":"ABB XT4SU3250BFF000XXX XT4S 1-pole MCCB, 250 A TMA trip, wal","metaDescription":"ABB XT4SU3250BFF000XXX XT4S molded case circuit breaker, 1-pole, 250 A TMA trip (1250-2500 A adjustable), wall-mount.
