The fixed trip range is 175–1750 A (the magnetic instantaneous pickup), so it clears short-circuit faults rapidly while the thermal element handles overloads on a slower curve. Frame mounting means it bolts into a switchboard or panel chassis, not a DIN rail; plan for bus-bar connections and a cutout that accommodates the XT3N footprint. ## Deployment context: frame-mount breaker in a distribution panel This is a frame-mounted breaker intended for fixed installation in a low-voltage switchboard or motor control center. It connects via front flat terminals — no plug-in base, no draw-out cradle. The thermal-magnetic design suits it for feeder protection in commercial and industrial distribution where you need adjustable overload protection and fixed short-circuit pickup. The 3-pole configuration covers three-phase loads; verify that your system's available fault current stays within the breaker's interrupting rating (not listed here, but required for coordination).","metaTitle":"ABB XT3NU3175AFF000XXX Tmax Breaker Frame, 225 A, 3-Pole","metaDescription":"ABB XT3NU3175AFF000XXX Tmax XT3N molded case breaker frame, 225 A, 3-pole, thermal-magnetic fixed trip.
