    Tips: Application of AC vacuum contactor

    AC vacuum contactors are widely used for the breaking of electric power and the control of electric circuits. It uses the main contact to open and close the circuit, and the auxiliary contact to execute the control command. The main contact generally has only a normally open contact, while the auxiliary contact often has two pairs of contacts with normally open and normally closed functions. Small contactors are often used as intermediate relays to cooperate with the main circuit. The contacts of the AC vacuum contactor are made of silver-tungsten alloy, which has good electrical conductivity and high temperature ablation resistance. The AC vacuum contactor is an intermediate control element. Its advantage is that it can frequently turn on and off the circuit and control the large current with a small current. The AC vacuum contactor working with the thermal relay can also play a certain role in overload protection for the load equipment. Because it relies on electromagnetic field suction to make and break work, compared to manual opening and closing circuits, the AC vacuum contactor is more efficient and more flexible in use. It can open and close multiple load lines at the same time, and it also has a self-locking function. After manually short-circuiting and closing, it can enter the self-locking state and continue to work.
