AC contactor is an automatic switching electrical appliance that turns on or off the main circuit of the motor or load, and is an electrical appliance that uses electromagnetic force to close or disconnect the switch, which is suitable for frequent operation, long-distance control of strong current circuits, and has the protection performance of low voltage release.
AC contactors often use three arc extinguishing methods: double-fracture electric arc extinguishing, longitudinal seam arc extinguishing and grid arc extinguishing. It is used to eliminate the arc generated by the dynamic and static contacts in the process of opening and closing. Contactors with a capacity of more than 10A have arc extinguishing devices. AC contactors also have auxiliary components such as reaction springs, buffer springs, contact pressure springs, transmission mechanisms, bases and binding posts.
