Summary

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.

Ambient condition

1. Altitude: ≤ 1000m;
2. Ambient temperature: -25℃ ~+40℃ ;
3. Relative humidity: daily average ≤ 95％ , monthly average ≤ 90％ ;
4. Earthquake intensity: ≤ 8 grade;
5. Applicable occasions should free from inflammables, explosives, corrosives and severe vibration.

Product feature
