GN30-12 Disconnecting Switch
Description:
GN30-12(D) disconnect switch is an indoor electric apparatus of rated voltage 12kV, three-phase AC50/60Hz. It is used to make the 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 through the installation as well. It is made as per IEC62271-102
| 1. Scientific design and innovative structure |
| 2. Contacting points distribute on two planes, small operating moment, and release pressure to small and easy adjustment |
| 3. Improved driving and conducting part |
| 4. Column moving contact that can decrease operating strength and ensure reliability of circuit conduction |
