Product details

The XT1NU3025AFF000XXX is a 3-pole molded case breaker rated for 600Y/347 VAC and 500 VDC, with an adjustable amp range from 25 to 500 A. That 500 VDC rating means it handles DC bus circuits in drives or solar combiner panels — not just AC distribution. The wide amp range lets you dial in the trip setting on site, so one frame size covers multiple load currents in the panel.

Panel Fit & Mounting

The 3-pole footprint matches standard MCC bucket cutouts. Terminal lugs accept copper or aluminum conductors up to the rated ampacity; torque values per the nameplate label.
