The ABB AF1350‑30‑11 is a heavy‑duty 3‑pole low‑voltage contactor rated for 1350 A AC‑1, designed for switching high‑current industrial power circuitsABB Group. It is equipped with 1 NO +1 NC built‑in auxiliary contacts, and adopts ABB’s AF electronic coil technology supporting wide 100‑250 V AC/DC control supply, which resists voltage fluctuations and reduces holding power consumptioneero. Integrated surge suppression improves anti‑interference performance in unstable power networks. This unit is widely used for motor control, main circuit switching and soft‑starter bypass duties within industrial power panels.

Series

AF1350‑30‑11 belongs to ABB large‑size AF contactor series, block‑type modular construction allows flexible expansion with extra auxiliary contact blocks and mechanical accessorieseero. The AF series features universal AC/DC coil, noise‑free operation and short‑time voltage‑dip tolerance, differentiating it from conventional contactors. Model suffix defines pole configuration and auxiliary contact layout; AF1350‑30‑11 stands for 3 main poles plus one normally‑open and one normally‑closed auxiliary contactABB Group.

Application Fields

Commonly deployed in power plants, mining infrastructure, heavy manufacturing, wind power and large water‑treatment projects. Typical uses include main incoming switching for generator sets, large‑capacity motor control, bypass contactors for soft‑starters and variable‑frequency drives, and high‑current distribution cabinet switching taskseero. It serves for new panel build‑outs as well as retrofit and spare‑part replacement of existing low‑voltage control systems.

Summary

ABB AF1350‑30‑11 delivers robust high‑current switching capability with the advantages of wide‑range electronic coil and modular expandability. It is a reliable solution for heavy‑load industrial power control. Proper matching of control voltage and auxiliary accessories should be followed to meet site operational requirements.Tags: ABB, AF1350‑30‑11, high‑power contactor, low‑voltage switching, motor control
