The 40-400 A range covers a wide band of motor and feeder protection; the fixed curve means no interchangeable trip plugs or electronic adjustments, so verify the installed setting matches the load's full-load ampere rating. In a 3-pole configuration, it switches all three phases simultaneously, which is standard for three-phase branch circuits and motor disconnects.","metaTitle":"ABB XT2LU3040ADD000XXX XT2L 125 TMF 40-400 3p F F UL/CSA, cu","metaDescription":"ABB XT2LU3040ADD000XXX molded-case circuit breaker, XT2L 125 TMF 40-400 3p F F UL/CSA.
