The ABB AF400‑30‑11 is a heavy‑duty three‑phase power contactor from ABB’s AF series — designed for motor starters, industrial load switching, and distribution applications. It provides three main normally‑open contacts for controlling 3‑phase power circuits, plus built‑in auxiliary contacts for control or signalling. The contactor supports a wide range of coil/control voltages (AC or DC depending on version) and is suitable for high-current, high-power applications (motors, large loads, industrial equipment). Its robust construction, high breaking and making capacity, and IEC/UL compliance make it a versatile choice for demanding power control and motor‑control applications.
