The XT1SU3125AAA000XXX: As an XT1S molded case breaker, it mounts directly onto the DIN rail or panel-mount baseplate common in ABB switchgear and distribution boards. The 3-pole design occupies a single modular width, leaving adjacent slots for additional breakers, contactors, or auxiliary devices. Verify the busbar system matches the line-side connection pattern — XT1S breakers accept standard ABB busbar kits for daisy-chaining multiple units.

The XT1SU3125AAA000XXX is a 3-pole device, meaning it switches and protects all three phases of a three-phase power circuit.
Both units share the same XT1S frame, pole count, and mounting footprint, so they fit the same panel cutout and bus connection pattern. However, the XT1SU3125AAA000XXX is rated for a higher current — verify the busbar and cable sizing can handle 125 A before substitution.
