Rated for 25 kAIC at 480V, the XT2NU3100BFF000XXX is a 100A, 3-pole MCCB from the SACE Tmax XT series.

It mounts into ABB ReliaGear neXT panelboards and SB switchboards. Facility managers can use this to replace legacy GE Spectra SEHA36AT0100 and ABB Tmax T3N100TW breakers. The XT2 frame is double-insulated and HACR rated.Specifications
