The ABB AF305‑30 is a heavy‑duty three‑phase contactor designed for switching and controlling industrial power circuits and motors. It belongs to ABB’s AF series of contactors, which are widely used in motor control, distribution, bypass, and isolation applications in industrial and commercial electrical systems. The device features three main power poles and can be equipped with auxiliary contacts for status feedback and control logic. Its coil accepts a broad range of control voltages in both AC and DC, and built‑in surge suppression helps reduce energy consumption and improve reliability. The robust design ensures distinct switching performance, even under unstable supply conditions, and allows use in demanding environments with wide voltage variations.
