The three-pole design with front terminals suits it for panelboard or distribution-board mounting where you need overcurrent protection on a 400 VAC or 480 VAC feeder. The 125 A frame and TMF 45-500 trip unit mean the breaker is sized for a circuit where the continuous load is up to 125 A, and the thermal-magnetic trip provides both overload (thermal) and short-circuit (magnetic) protection. The \"45-500\" indicates the magnetic pickup range — typically 5x to 10x the rated current, so it clears faults fast without nuisance tripping on motor inrush. UL/CSA listing certifies it for North American panel installations per UL 489 and CSA C22.2 No. 5.","metaTitle":"ABB XT1SU3045AFF000XXX Molded Case Circuit Breaker, 125 A TM","metaDescription":"ABB XT1SU3045AFF000XXX molded case circuit breaker, 125 A TMF trip, 3-pole, current lifecycle stage.
