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.","metaTitle":"ABB XT1SU3125AAA000XXX XT1S, 3-Pole, Current Lifecycle","metaDescription":"ABB XT1SU3125AAA000XXX XT1S 3-pole component.
