The ABB A210‑30‑11 is a 3‑phase AC contactor from ABB’s “A‑line / A‑series,” designed for industrial and commercial use. It is intended for switching three‑phase motors or high‑power circuits, and can be used for motor starting, load switching, isolation, bypass, or power‑distribution control. The contactor features three main power contacts (3‑pole), plus auxiliary contacts for signalling or control logic. It supports a broad range of control (coil) voltages and is built to handle heavy-duty loads, making it suitable for motors, pumps, compressors, or general industrial power switching.
