The ABB A260‑30‑11 is a heavy‑duty 3‑pole AC contactor from ABB’s “A‑line” series, designed to switch three‑phase motors or other high‑power AC loads. It provides main contacts for power switching plus an auxiliary contact block for control or signalling. The contactor supports a wide range of coil/control voltages and is suitable for use in industrial, commercial, or power‑distribution panels where reliable switching of high currents and high voltages (up to 690 V) is required. Common applications include motor start/stop, motor bypass or isolation, switching of heavy loads, and general three‑phase power circuit control.
