The ABB AF1250‑30‑11 contactor (catalog number 1SFL647088R7011) is a heavy‑duty, three‑phase power contactor designed for industrial power switching applications such as isolation, bypass, distribution, and motor control in high‑current circuits. It features a block‑type design with three main poles and built‑in auxiliary contacts and accepts a wide control voltage range suitable for AC and DC operation. This contactor is commonly used where reliable switching of large loads up to high voltages is needed.
