VI For Contactor
Vacuum Interrupters For Contactor are used for connecting and breaking AC main circuits and large-capacity control circuits over long distances and frequently. Such as for coal mining, chemical industry, metallurgy, cement and other industries have explosion-proof, anti-corrosion and fire prevention requirements as well as places with harsh environments. The advantage of vacuum contactor is that it can be operated frequently to play the role of control, and it can also open and close the short-circuit current for short-circuit protection. Hongfa's vacuum interrupter chamber for contactor adopts one time sealing and discharging process, which is characterized by high vacuum degree, good insulation strength, low cut-off value and long service life.
