Product Description

  VS1-12 Indoor High Voltage Vacuum Circuit Breaker is three-phase AC 50Hz, Rated voltage of 12kV indoor device, For industrial and mining enterprises, power plants and substations as electrical equipment control and protection purposes, and for frequent operation of the place. It can be fixed in a switch cabinet or installed on a handcart. Stable performance and easy installation.
Applying Ambient Conditions:
• Ambient temperature: not higher than +40°C, not less than −10°C (at −30°C to allow storage and transportation).

• Altitude: not exceed 1000m.

• Relative humidity: daily average of not more than 95%, saturated vapor pressure on the average of not more than 2.2×10-3MPa, On average not more than 1.8× 10-3MPa.

• Earthquake intensity: not more than eight.

• No fire, explosion hazard, serious filthy, chemical corrosion, as well as places of intense vibration.

"High voltage vacuum circuit breaker" is named for its arc extinguishing medium and the insulating medium of the contact gap after arc extinguishing are high vacuum; Vacuum circuit breaker has the advantages of small size, light weight, suitable for frequent operation, arc extinguishing without maintenance, and is widely used in distribution network.

Vacuum circuit breakers usually have multiple voltage levels. Low-voltage type is generally used for explosion-proof electrical use. Like coal mines and so on.
