Product details

Panel fit and peer comparison

The XT1SU3125AFF000XXX shares the same XT1S frame as the 90 A variant XT1NU3090AFF000XXX — same 3-pole footprint, same mounting pattern. If your panel was wired for the 90 A version, this 125 A unit drops in without rewiring or drilling new holes. The only difference is the higher continuous rating, which gives you headroom for load growth or a more conservative thermal margin.

Sourcing posture

Because the lifecycle stage is current, this part is sourced through standard ABB distribution channels. No last-time-buy clock to watch.
