The ABB XT1NU3040AAA000XXX is a Tmax XT1 molded case circuit breaker, 40 A, 3-pole, rated 480 VAC with a 22 kA interrupting capacity.
Panel mount — fits a standard cutout for the XT1 frame. The fixed thermal-magnetic trip unit is non-interchangeable, so the 40 A rating is locked at order; no field adjustment. Three-pole configuration covers three-phase loads — motors, feeders, lighting panels. Terminals are front flat, which simplifies bus-bar or cable landing in a tight enclosure.
22 kA at 480 VAC. That's the maximum fault current this breaker can safely interrupt at that voltage.
