The ABB XT1NU3090AFF000XXX is a 3-pole thermal-magnetic molded case circuit breaker on the XT1N 125 A frame, fixed at 90 A and rated for 600 VAC. It ships with front flat terminals for panel wiring. This is the fixed-amp version — the trip unit is not field-adjustable, so the 90 A rating is the protection setting you get out of the box.
