ABB XT1N125 3 Pole 15 Amp 600 Volt Circuit Breaker

ABB SACE Tmax XT XT1N125 three-pole molded-case circuit breaker provides 15 A per pole of overcurrent protection in 600 V class systems. It is built on the XT1N125 frame size (125 A frame) and uses a Thermomagnetic (TMF) trip unit to deliver both thermal overload protection and magnetic short‑circuit protection. Rated for up to 600 V AC (600Y/347 V) and UL/CSA listed for North American installations, this device is designed for use in panel boards, switchboards, and motor-control centers where three-phase protection is required, with three poles that trip together to isolate all supply phases. Typical applications include protecting feeders, lighting, and small motor circuits in commercial or light-industrial environments, and the XT1N125 frame is intended for installations where a compact, standardized 3‑pole protective device is beneficial within a 125 A frame class.
