The TMF trip unit provides a fixed thermal element for overload protection and a magnetic element for short-circuit protection, with the continuous current adjustable between 100 and 1000 A via the rating plug. The 125 A frame size means the breaker's physical housing and bus connections are sized for that maximum continuous current, so the adjustable trip range (100-1000 A) lets you dial in the exact protection setting for the downstream load — useful when the same frame is used across multiple panel designs with different cable or busbar ratings. The UL/CSA listing is the key authority signal: it certifies compliance with UL 489 (molded-case circuit breakers) and the corresponding Canadian standard, which is required for service-entrance or feeder applications in North American panels. ## Deployment context This MCCB mounts into a standard panelboard or switchboard enclosure with busbar or cable connections on the line and load sides. The three-pole configuration suits three-phase power distribution — feeding a motor control center, a distribution panel, or a large single load like a chiller or compressor. The UL/CSA listing means it is accepted by AHJs (authorities having jurisdiction) for service-entrance equipment in North America without additional third-party evaluation.","metaTitle":"ABB XT1HU3100AYD000XXX NEXT1H 125 TMF 100-1000 3P F F UL/CSA","metaDescription":"ABB XT1HU3100AYD000XXX NEXT1H 125 TMF 100-1000 3P F F UL/CSA.
