GN19 Indoor high voltage isolation switch

  • Product Detail

GN19 Indoor high voltage isolation switch

      Isolation switch is designed to provide safety isolation from high voltage without load for the purpose of installation and maintenance. Our Serie GN19-12 are indoor HV isolation switches with three-phase AC 50Hz and rated voltage of 12kV. It meets the requirements of GB1985-2004,GB/T11022-1999,and IEC62271-102, providing a more reliable performance by replacing traditional porcelain isolator with Epoxy resin.
