GN30-12(D) disconnect switch is an indoor electric apparatus with rated voltage 12kV, three-phase AC50/60Hz. It is used to make break and transfer current for HV electric apparatus under situations with voltage and no-load.The switch applies rotary moving contact which is mounted on the switchgear easily. It adopts wall installation as well.
