ABB XT2HU3060ABB000XXX XT2H 125 TMF 60-600 3P F F UL/CSA

The XT2HU3060ABB000XXX: The TMF trip unit covers a 60–600 A continuous current range — that's the adjustable thermal pickup for overload protection and a fixed magnetic instantaneous for short-circuit. At the top end, 600 A handles large motor feeders or main distribution panels; at the low end, 60 A suits branch circuits. The XT2H frame's interrupting capacity is sized for industrial panelboards where fault current levels are known. Three-pole construction means it switches all three phases simultaneously, standard for three-phase power distribution in North American UL 489 panels.
