The XT1HU3040AFF00NXXX: The TMF trip unit gives you adjustable thermal (overload) and fixed magnetic (short-circuit) settings across the 40-500 A range, which covers a wide band of motor and feeder protection needs. The 125 A frame means the breaker body itself is rated for that continuous current; the trip unit is what you dial in for the actual load. UL/CSA listing confirms it's accepted for North American panel installations without extra agency review.
