GN□-12 Indoor AC High Voltage Disconnect Switch

GN-12

Summary
GN□-12 indoor AC high voltage disconnect switch is an indoor electric apparatus of rated voltage12kV,three-phase AC 50/60Hz.It is especially applicable in small switch cubicle occupying small space. The switch interlock well (the main blade and earthing blade can not close simultaneously), operate easily and reliably.
Ambient condition
1. Altitude: ≤1000m;
2. Ambient temperature: -25℃~+40℃;
3. Relative humidity: daily average ≤95%, monthly average ≤90%;
4. Earthquake intensity: ≤8 degree;
5. Applicable occasions should free from inflammables, explosives, corrosives
and severe vibration.
Product feature
1. Scientific design and innovative structure.
2. Small volume and light weight.
3. Easy maintenance and long service life.
4. The main balde and earthing blade are interlock well to avoid simultaneous operation.
