The ABB AX205‑30‑11‑80 is a three‑pole AC magnetic contactor designed for robust industrial and commercial use in three‑phase power switching and motor control applications. It features three main normally open contacts and built‑in auxiliary contacts (1 NO + 1 NC) for control and signaling. The device is intended for control circuits with a coil voltage around 220–230 V AC (50 Hz) or 230–240 V AC (60 Hz) and can handle heavy switching loads up to systems rated around 690 V AC or above, making it suitable for motor starters, power distribution switching, and general industrial control panels.
