The ABB A12‑30‑10 is an electromechanical AC contactor designed for controlling three‑phase motors and power loads. It uses a coil (specified by voltage) to electrically actuate the main contacts, enabling reliable switching of power circuits up to low‑voltage distribution levels. The compact block‑type design makes it suitable for DIN‑rail or panel installations, and the contactor can be used with auxiliary contacts and overload relays to form full motor starter units.
