The ABB AX12‑30‑10‑80 is a three‑pole AC magnetic contactor designed for industrial and commercial electrical control systems. It is used to switch and control three‑phase power circuits, such as motors, lighting, heating, and general loads up to 690 V AC. This contactor features a block‑type design with three normally open main contacts and one normally open auxiliary contact for control and signaling. It is intended for operation with an AC coil voltage around 220–230 V 50 Hz or 230–240 V 60 Hz, and it is suitable for use in motor starters, control panels, and automation applications
