Tips: Advantages of ac vacuum contactors for sale on CCHN

CCHN ac vacuum contactor has strong arc extinguishing ability, good pressure resistance, high operating frequency, long life, no arc spray, small size, light weight, and long maintenance cycle. The process requirements for the vacuum interrupter of the ac vacuum contactor are very high. If the process is poor, the vacuum of the interrupter is easy to drop. If the contact material of the ac vacuum contactor is not good, the phenomenon of "intercepting over-voltage" will occur when the current is interrupted. That is, when the current is interrupted, due to the strong arc extinguishing ability of the vacuum interrupter, the arc current is not cut off naturally at zero crossing, but suddenly drops from a certain value of the current to zero, resulting in a high overvoltage. Intercepting over-voltage will endanger the safe operation of electrical equipment.
