For a panel builder coordinating with downstream breakers, the TMF's fixed magnetic pickup (typically 10× In for this family) sets the selectivity limit. Upstream coordination requires checking the let-through energy (I²t) curves against the downstream device's withstand. ## Panel integration The F F terminals accept busbar or cable connections; torque to the value stamped on the breaker (typically 2.5–3.5 Nm for the line/load lugs).","metaTitle":"ABB XT1HU3050AFD000XXX XT1H 125 A TMF 50-500 3P, current lif","metaDescription":"ABB XT1HU3050AFD000XXX XT1H 125 A TMF 50-500 3P F F UL/CSA molded case circuit breaker.
