Product Description

     Sanhe SEK intelligent permanent magnet vacuum contactor, as a new generation of medium voltage vacuum contactor, is fitted a permanent magnet mechanism to close/open the dynamic and static contacts of the vacuum interrupter in a direct motion. SHVC intelligent permanent magnet vacuum contactor can be widely used in the three-phase AC system below 12kV and rated frequency 50Hz/60Hz where multiple opening and closing operation cycles are required, and it is especially suitable for users who operate frequently. SHVC intelligent permanent magnet vacuum contactor adopts a wide-voltage, high-efficiency and reliable electronic control module, and uses STM32 mainstream chips inside. It has the characteristics of fast response to closing and opening, LED indication for closing and opening, and alarm auxiliary contact output.
     SHVC intelligent permanent magnet vacuum contactor has the characteristics of energy saving, material saving, fireproof, explosion-proof, small size, long life, low maintenance cost, reliable operation and no pollution.  It is widely used in the control and protection of power transmission and distribution systems in the fields of electric power, machinery, metallurgy, mining, petroleum, chemical industry, railway, broadcasting, communications, and transportation. Using the ideal technology of breaking current in a vacuum environment, as well as extremely high reliability and compact structure, the contactor can be used under particularly harsh conditions. They are suitable for control and protection (with fuses) circuits, substations and distribution stations, motors, transformers, capacitor banks, etc.
