The ABB AF40‑30‑00‑11 is a three‑pole AC contactor from ABB’s AF Series designed for switching and controlling three‑phase electrical power circuits, especially for motor control and general power switching applications. It is suitable for use in control panels, automation systems, and industrial electrical installations where reliable switching of heavy loads is required. AF Series contactors feature an electronic coil interface with wide control voltage tolerance and built‑in surge suppression, reducing the need for external suppression devices and improving operational stability.
