The 18 kAIC at 600Y/347 VAC tells you it can safely interrupt a fault up to 18,000 symmetrical amps at that voltage. The 3-pole configuration switches all three phases simultaneously, which is standard for three-phase loads; for single-phase 277 V lighting circuits off a 480Y/277 V system, you'd land the load on one pole and leave the others unused or as spares. The fixed front flat terminals accept standard bus bar or lug connections — no special adapter required for panel wiring. The compact footprint (roughly 76 mm per pole width) means it fits a standard 3-pole MCCB slot in a 600 V panelboard without crowding adjacent devices.","metaTitle":"ABB XT1NU3025AAA000XXX Molded Case Breaker, 25A, 3P, 600Y/34","metaDescription":"ABB XT1NU3025AAA000XXX molded case circuit breaker, 25A, 3-pole, 600Y/347VAC, 18kAIC.
