Product details

The ABB XT1NU3100AAA000XXX is a Tmax XT1N molded case circuit breaker (MCCB) rated 100 A continuous, 3-pole, 600 VAC, with a thermal-magnetic fixed trip unit set at 100 A. Frame-mounted — meaning it bolts into a panel or switchboard, not a DIN rail.

This breaker lives inside a distribution panel or motor control center. The frame-mount form factor means you bolt it to a backplate or busbar system — no DIN-rail clip. The fixed front flat terminals accept busbar or cable lugs directly. Panel builders should plan for the XT1N frame footprint and the 3-pole width.

Frequently asked questions

How do I get current pricing and availability for XT1NU3100AAA000XXX?

Submit an RFQ through this listing. Pricing and stock are confirmed at quote time through independent distribution — no fixed price or live count is published here.

What is XT1NU3100AAA000XXX's listed amps and poles?

Rated 100 A continuous, 3-pole, 600 VAC, with a thermal-magnetic fixed trip set at 100 A.

Will XT1NU3100AAA000XXX drop into a panel specified around XT1NU3090AFF000XXX without rewiring?

Both use the same Tmax XT1N frame and 3-pole footprint, so the mechanical fit is identical. The difference is the trip rating: 100 A on this breaker versus 90 A on the peer. If the panel bus and cable are sized for 90 A, a 100 A breaker is a drop-in — no rewiring needed, but verify the upstream protection and conductor ampacity are rated for 100 A.
