The ABB AF09‑30‑10‑11 is a compact 3‑pole AC contactor designed for industrial and commercial control applications. It is used to switch and control three‑phase power circuits, including motors and other inductive or non‑inductive loads. The contactor features an electronic coil interface that accepts a wide range of AC or DC control voltages, and includes one built‑in normally open auxiliary contact for control or signaling purposes. Its block‑type design and DIN‑rail compatibility make it suitable for automation panels, motor starters, HVAC systems, and general power switching tasks.
