It uses a fixed thermal-magnetic trip unit — no interchangeable trip block — so the 50 A rating is built in. Panel-mount construction means it bolts into a switchboard or distribution panel, not a DIN rail. The 50 A rating suits motor branch-circuit protection at 480 VAC. The 3-pole configuration covers three-phase circuits; the frame is rated for 600 VAC. ## Integration note Panel mount — the breaker bolts directly to a backplate or busbar system. The extended front terminals (part of the order-code suffix) provide extra clearance for lug connections and make wiring easier in a crowded enclosure. No DIN-rail adapter; plan for drilling and tapping the mounting holes.","metaTitle":"ABB XT1NU3050AAA1A0XXX Molded Case Breaker, 50 A, 3-Pole, 48","metaDescription":"ABB XT1NU3050AAA1A0XXX molded case circuit breaker, 50 A, 3-pole, 480 VAC.
