The UL/CSA listing on the description means it carries the approvals needed for North American panel builds — no separate fuse holder or supplementary protector required for branch circuit protection in a 480Y/277 V distribution. The 125 A frame size with a TMF trip unit adjustable 15-400 A means this breaker covers a wide motor and feeder range on a single physical footprint — useful when stocking one frame for multiple branch ratings. The TMF (thermal-magnetic fixed) trip provides inverse-time overload protection and instantaneous short-circuit response; the 3-pole configuration suits three-phase loads up to 400 A, with the UL/CSA mark confirming compliance for US and Canadian installations. No separate fuse or supplementary protector is needed for branch circuit protection in a 480Y/277 V distribution panel.","metaTitle":"ABB XT2NU3015AFF000XXX XT2N MCCB, 125 A TMF, 15-400 A, 3P, U","metaDescription":"ABB XT2NU3015AFF000XXX XT2N molded case circuit breaker, 125 A frame, TMF trip unit 15-400 A, 3-pole, UL/CSA.
