The ABB AF contactor is a 3 or 4-pole electromechanical device used for switching and controlling electric motors and other loads in industrial applications. It is designed to work in both AC and DC networks without changing the coil, thanks to its advanced electronic coil technology.
Main application:
Starting and stopping electric motors, controlling resistive or inductive loads, and automation systems.
Key benefits:
1. Universal electronic coil: supports control voltages from 24 to 500 V AC/DC, reducing the number of required part numbers [4].
2. High reliability: less electrical arc wear, faster and more accurate operation [6].
3. Voltage fluctuation tolerance: ideal for unstable network conditions [3].
4. Optimized stock and design: simplifies logistics and panel design
