The ABB XT1N 160 3‑pole 125 A MCCB is a fixed molded‑case circuit breaker designed to protect three‑phase electrical circuits in industrial and commercial low‑voltage installations. It uses a thermal‑magnetic (TMA) trip unit to provide reliable overcurrent and short‑circuit protection. The breaker is suitable for motor circuits, machinery, and general power distribution. Front-terminal mounting allows easy integration into control panels and distribution boards, with high breaking capacity to ensure safe operation.
