[0002] AC contactors are mainly used to connect and disconnect AC circuits. They mainly include the following three parts: (1) electromagnetic system, including attraction coil, moving iron core and static iron core; (2) contact system, including three sets of main contacts and one or two sets of normally open and normally closed auxiliary contacts, which are interconnected with the moving iron core; (3) arc extinguishing device. Generally, AC contactors with larger capacity are equipped with arc extinguishing devices to quickly cut off the arc and avoid burning the main contacts. AC contactors with smaller capacity rely on arc-isolating plates set on the shell to isolate the arc.
