DESCRIBE

The ABB XT2N 160 TMD 32/320 3‑pole FF is a fixed (non‑withdrawable) molded‑case circuit breaker designed for protection of three‑phase electrical circuits. It uses a thermomagnetic (TMD) trip unit with adjustable overload and short‑circuit settings. This breaker provides reliable over‑current and short‑circuit protection for industrial or commercial low‑voltage power distribution, motor circuits, or general machinery protection. It is designed for front‑terminal (FF) installation and supports both AC and DC supply conditions. The rugged design and broad range of current settings make it suitable for a wide variety of applications where adjustable protection and high breaking capacity are required.
