The XT1NU3100AAAB00XXX: The closest peer in the same XT1N frame is XT1NU3090AFF000XXX, rated 90 A instead of 100 A. Both are 3-pole, same mechanical footprint, same mounting. The 10 A difference matters for motor full-load current matching — if the load draws 95 A, the 100 A unit carries it; the 90 A unit would trip on overload. For a panel already wired for the 90 A version, the 100 A version drops in without rewiring — same lug size, same bus spacing.
