Introduction
As a new generation of high-voltage vacuum contactor products, Sanhe SEK series monostable permanent magnet high-voltage vacuum contactor adopts a wide voltage electronic module to control the up and down direct movement of the monostable permanent magnet mechanism, so as to frequently switch on and cut off the normal working current, which is suitable for the control and protection of motor, transformer, reactive power compensation and other equipment.
