Product details

The ABB XT1SU3100AFF000XXX is a 3-pole molded case circuit breaker from the XT1S 125 TMF family, rated 100 A continuous at 480 VAC. Panel-mount construction, so it bolts into a switchboard or distribution panel rather than snapping onto a DIN rail.

Panel-mount form factor means the breaker mounts directly to a backplate or sub-panel with bolts, not a DIN rail. The XT1S 125 TMF frame is a compact 3-pole design, so it fits standard MCCB cutouts in switchboards and distribution panels. Terminal connections accept copper or aluminum conductors sized for the 100 A rating.

Frequently asked questions

What is the interrupting rating of XT1SU3100AFF000XXX?

35 kA at 480 VAC, which is the maximum fault current this breaker can safely interrupt at that voltage.

Will XT1SU3100AFF000XXX drop into a panel specified around XT1NU3090AFF000XXX without rewiring?

The XT1SU3100AFF000XXX shares the same XT1S 125 TMF frame and panel-mount footprint as the 90 A XT1NU3090AFF000XXX, so it bolts into the same cutout and uses the same terminal layout. The difference is the 100 A continuous rating versus 90 A — if the upstream protection and conductor sizing support 100 A, it's a direct mechanical swap.

Where can I buy XT1SU3100AFF000XXX and how is it quoted?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
