The ABB AF300‑30‑11 is a heavy‑duty 3‑pole AC contactor, designed for switching and controlling three‑phase motors, heavy loads, and general power circuits. It features three main normally‑open (NO) contacts for the main power circuit and includes auxiliary contacts (1 NO + 1 NC) for control or signalling needs. The contactor supports a wide control (coil) voltage range (AC or DC, depending on variant), making it flexible for global applications. With robust construction, high rated current, and high breaking/making capacity, the AF300‑30‑11 is well suited for industrial motor starters, large machinery control, power distribution panels, and other demanding electrical installations.
