The ABB AF50‑40 is a robust industrial power contactor designed for switching and controlling three‑phase electrical power circuits. It features a block‑type configuration with four main poles, allowing it to handle AC loads such as motors, heaters, and other resistive or slightly inductive applications. The contactor is equipped with an electronic coil interface that accepts a wide range of control voltages in both AC and DC, enabling flexible operation in different control systems. It offers reliable performance even under voltage fluctuations and dip conditions, with compact dimensions for panel mounting. The design supports auxiliary contact blocks and accessories for expanded control and signalling.
