ABB SACE XT1N-D125-3P Circuit Breaker

ABB SACE Tmax XT1N-D125-3P is a 3‑pole molded‑case circuit breaker (MCCB) from ABB’s SACE Tmax XT family, rated for 125 A (In) and up to 600 V, with a twist‑handle mechanical operation for manual on/off control. The XT1N‑D125‑3P variant is UL/CSA listed for North American electrical systems, making it suitable for protecting three‑phase feeders in industrial and commercial low‑voltage distribution panels from overloads and short circuits. Built on the XT frame, this device combines a compact 3‑pole form factor with ABB’s Tmax XT protection technology, designed to intercept fault currents and provide clear, mechanical disconnection in standard MCCB enclosures. In applications ranging from small industrial feeders to critical distribution circuits, the XT1N‑D125‑3P delivers reliable overcurrent protection in a rugged, field‑installable package that integrates with ABB’s broader Tmax XT product ecosystem.
