ABB XT1H125 Drawout Molded Case Circuit Breaker

ABB SACE Tmax XT XT1H125 is a three‑pole, drawout molded‑case circuit breaker built around ABB’s Tmax XT platform, configured in the 125 A frame for use in distribution panels and switchgear up to 600 V. This UL/CSA‑listed device is designed for 3‑phase service and uses TMF (thermal‑magnetic) protection to interrupt overloads and short circuits with fast, reliable operation. Rated for 600Y/347 VAC in standard wye configurations, the XT1H125 also supports up to 480 VAC delta in applicable UL configurations, making it versatile for a range of commercial and light‑industrial installations. The drawout design facilitates safe inspection and replacement within panelboards, switchboards, or MCCs while maintaining a compact footprint for a 125 A frame. As part of the SACE Tmax XT family, it provides consistent protection with modular integration alongside other XT MCCBs across distributed electrical systems. Ideal for distribution panels in commercial buildings and light industrial facilities where dependable, code‑compliant overload and short‑circuit protection is essential.
