The ABB XT4NU3175AYJ000XXX is a NEXT4N 250 TMF 175-1750 3P F F UL/CSA molded-case circuit breaker. The TMF designation indicates a thermal-magnetic fixed trip unit, rated 175 A with a 1750 A instantaneous magnetic trip — a standard combination for motor branch-circuit protection in UL 489 panels. The 3P F F marking means three-pole, with fixed front terminals front-connected, and the UL/CSA suffix confirms it carries the necessary approvals for North American installations.
