Product Description

1.General description

    VACYC permanent magnet AC M.V. vacuum contactor and VACFC series AC M.V. vacuum contactor-fuse combination apparatus(F-C) are three-phase AC indoor middle voltage switch device suitable for AC 50-60Hz and the rated working voltage of main circuit is 7.2kV and 12kV.It has the advantages of flexible function combination,compact and reliable structure,multiple protection functions,long service life and allowed frequent operation.It can be widely used to open and close load circuits such as AC motor and transformer,and can also be used for capacitor reactive power compensation.
    VACFC series combination apparatus adopt modular combination structure,which can be used by single contactor or combined into F-C,and can be fixed or drawout moving type.The drawout type can be used with KYN28A(GZS1) intermediate cabinet with width of 650mm or 800mm,and can be used to replace VSC/P contactor.
   VACFC contactor can be used alone or with other electrical apparatus.
   VACFC permanent magnet AC M.V. vacuum contactor and VACFC series AC M.V. vacuum contactor-fuse combination apparatus meet the requirements of national standards GB/T 14808 and GB/T 11022.
