The ABB AF1250-30-11 is a heavy‑duty, 3‑pole three-phase power contactor from ABB’s AF series. It is designed for industrial motor control and power switching applications, handling substantial current demands for motors, power circuits, and general industrial loads. The contactor supports a wide-range electronic control (coil) voltage, allowing flexible AC/DC coil operation and enhanced tolerance to voltage fluctuations or dips, which improves reliability in varied environments. Its block-type modular design—with three main contacts and an auxiliary contact (1 NO + 1 NC)—makes it suitable for motor starting, isolation, bypass, power distribution, and control-center installations. The AF1250-30-11 is engineered for robustness, long service life, and stable performance under heavy workloads.
