It comes with front flat terminals for panel wiring and uses a frame mount — no DIN-rail adapter needed, it bolts directly into the switchboard or enclosure bus structure. ## What the 125 A rating means for your panel That sets the maximum load you can hang downstream: a 125 A feeder feeding a sub-panel, a large motor control center bucket, or a group of smaller branch circuits. The thermal-magnetic trip gives you an inverse-time thermal element for overload protection and a magnetic instantaneous element for short-circuit protection. The fixed trip range (70–700 A) means the magnetic pickup is factory-set; you adjust the thermal setting via the dial on the front face.","metaTitle":"ABB XT1NU3070AFF000XXX Tmax XT1N 125A 3-Pole Thermal-Magneti","metaDescription":"ABB Tmax XT1N frame breaker, 125 A, 3-pole, thermal-magnetic fixed trip 70-700 A, front flat terminals.
