The ABB A50‑30 series are three‑pole AC contactors designed for controlling and switching three‑phase power circuits in industrial, commercial, and utility applications. These devices are part of ABB’s A‑series contactor family, commonly used for motor control, general power switching, lighting, capacitor switching, and isolation tasks. They are engineered to operate reliably over a wide range of voltages and frequencies, with robust construction and easy integration into control panels.
