The A110‑30‑11 is a 3‑pole AC contactor from ABB’s A‑series, designed for general industrial power switching and motor control applications.It features 3 main contacts (normally open) for the main circuit and includes auxiliary contacts (1 NO + 1 NC) for control or signaling circuits. The contactor is suitable for use with three‑phase loads, motor starters, and can handle up to specified voltage/current ratings per its frame size.The design supports screw/cable‑clamp terminations, making it compatible with standard wiring practices in control panels and switchgear assemblies.
