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.
VS1 vacuum circuit breaker can perform frequent operations or break short-circuit current multiple times within the working current range; the mechanical life can be as high as 30,000 times, and the number of short-circuit current breaking times at full capacity can reach 50 times.
VS1 vacuum circuit breaker is suitable for reclosing operation and has extremely high operational reliability and service life.
VS1 vacuum circuit breaker (ordinary type) adopts a vertical insulating cylinder to protect against the influence of various climates; and in terms of maintenance and maintenance, it usually only needs to clean or lubricate the operating mechanism occasionally.
VS1 vacuum circuit breaker (pole type) adopts a solid insulation structure-integrated solid-sealed pole, which realizes maintenance-free.
The installation form of VS1 vacuum circuit breaker in the switch cabinet can be either fixed or withdrawable, and can also be installed on the frame for use
