ABB XT1N125 Molded Case Circuit Breaker

ABB SACE Tmax XT XT1N125 is a 3-pole molded-case circuit breaker designed for 125 A protection in 600 V three-phase distribution systems. As part of ABB’s Tmax XT family, this MCCB delivers reliable overcurrent protection for electrical panels and switchgear in commercial and industrial installations, with UL/CSA listings documented in ABB’s ecatalog. The XT1N125 variant is available in TMF (thermal-magnetic) trip-unit configurations, enabling tailored protection profiles across a range of applications while maintaining a compact frame that fits standard 3‑pole enclosures. This model supports easy integration into panel boards and distribution gear where robust, resettable protection is required at 600 V, and it is designed to coordinate with ABB’s accessory ecosystem of trip units and options offered for the XT family. The product’s 125 A rating and 3-pole arrangement provide balanced protection for three-phase circuits, helping prevent damage from overcurrent events and enabling quick interruption when faults occur. For engineers selecting protective devices, the XT1N125 sits within ABB’s SACE Tmax XT lineup known for modularity, regional listings, and compatibility with common 3P protection schemes in industrial facilities.
