ABB XT1SU3025AFF000XXX Molded Case Circuit Breaker

The ABB XT1SU3025AFF000XXX is a three-pole Tmax XT molded case circuit breaker (MCCB) from ABB’s Tmax XT family, designed to protect industrial and commercial low-voltage distribution networks by interrupting damaging short circuits and overcurrents in feeders and panels. Equipped with a thermal-magnetic TMF trip unit, it covers a current range of 25 to 500 A within the 125 A frame size, offering precise overload protection and rapid interruption for 3-phase circuits in 50/60 Hz systems. Rated for UL and CSA listings, the XT1SU3025AFF000XXX is configured for high-voltage distribution as 600Y/347/690 VAC variants and offers up to 22 kA interrupting capacity, making it suitable for motor feeders, bussing, and main service protection in industrial plants. Physical footprint is approximately 5.12 in high by 3 in wide by 2.75 in deep, with front-line/load-side connection provisions common to ABB MCCBs, aligning with standard panel cutouts and enabling straightforward replacement in existing Tmax XT installations.
