Listed lifecycle stage is current — meaning ABB still manufactures this order code and it has not been flagged for phase-out. That is the clean read for a BOM freeze: no PCN watch needed yet, no last-time-buy clock running. ## What the 3-pole rating means for fit Three poles means it switches and protects all three phases of a 400 V three-phase supply — the standard for motor feeders, small distribution subfeeds, and panelboard mains in European and IEC-style panels. The XT1H frame accepts plug-in accessories (auxiliary contacts, shunt trips, undervoltage releases) that snap into the same DIN-rail or screw-mount footprint without enlarging the enclosure cutout.","metaTitle":"ABB XT1HU3125MFF000XXX XT1H 125 A 3-Pole MCCB, Current Lifec","metaDescription":"ABB XT1HU3125MFF000XXX 3-pole MCCB, 125 A frame, current lifecycle.
