[0002] The electromagnetic direct-running AC contactor is a low-voltage electrical appliance in the field of automatic power supply control. The existing electromagnetic direct-running AC contactor is limited by the large volume of the U-shaped electromagnet. The equipped mechanical lock has to be installed on the side of the mechanism. The unbalanced pressure of the three contacts of the contactor causes the performance of the contactor to deteriorate
If it is not equipped with a mechanical lock, it will not only consume electricity, but also the on-off working state will be affected by the grid voltage. If the voltage is high, it will easily burn out the electromagnetic coil; contact
