The ABB XT3NU3125AFF000XXX is a Tmax XT3N frame breaker — 3-pole, 225 A fixed thermal-magnetic trip, frame-mounted with front flat terminals. Frame mounting means it bolts into a switchboard or panel bus, not a DIN rail — plan for bus-bar connections and a cutout in the gland plate.
The 225 A is the fixed continuous current rating — the breaker carries that load indefinitely at 40 °C ambient without tripping. The thermal-magnetic trip provides overload protection via a bimetal strip and short-circuit protection via a solenoid.
