The 125 A frame size means the breaker's physical dimensions and bus connections are sized for that continuous current; the TMF trip provides both thermal overload (inverse-time) and magnetic short-circuit (instantaneous) protection. UL/CSA listing confirms the breaker meets North American panelboard and switchgear standards, so it slots into a UL 489 or CSA C22.2 No. 5 panel without additional agency review.","metaTitle":"ABB XT1NU3125AFFBG0XXX XT1N 125A TMF 3P FF UL/CSA MCCB","metaDescription":"ABB XT1NU3125AFFBG0XXX XT1N 125A TMF 125-1250 3P FF UL/CSA MCCB.
