General industrial and commercial power control tasks
The ABB AX50‑30‑11‑80 is a three‑pole AC magnetic contactor designed for industrial and commercial electrical control systems. It is used mainly for switching and controlling three‑phase power circuits and motors up to 690 V AC. This contactor has a block‑type design with three main normally open contacts and includes one normally open (NO) and one normally closed (NC) auxiliary contact for control and signaling functions. It is suitable for use with AC control/coils at 220–230 V 50 Hz or 230–240 V 60 Hz, and it provides robust mechanical and electrical performance for general motor and power switching applications
