VSG-12

vacuum circuit breaker

VSG type indoor AC high-voltage vacuum circuit breaker is a kind of integrally sealed high-voltage switchgear with small size and compact structure. It is suitable for power systems with rated voltage of 12kV and three-phase AC 50/60Hz, used to control and protect frequently operated electrical equipment and circuits.

environmental conditions

1. Altitude: ≤1000m 2. Ambient temperature: -15°C~+40°C
3. Relative humidity: daily average ≤95%, monthly average ≤90%
4. Earthquake intensity: ≤8 degrees
5. Applicable occasions should be free of flammable, explosive, corrosive and violent vibration.
