12kV Embedded Pole Vacuum Circuit Breaker, vacuum circuit breaker
Product Detailed
1,perfect design,, 2,free maintance,no oil charging large capacity,no burning 3, vacuum circuit breaker

ZN63-12E(VS1) series of vacuum circuit breaker is three-phase A.C. 50Hz indoor high-voltage distribution device with 12KV rated voltage and below which can match with GZS1 type cubical switchgear. It is suitable to control and protect transmission and distribution system such as power generation plant and substation, especially used in the fields where it is frequently operated.The operating mechanism of this series of circuit breaker is that of spring energy-stored type which can be operated by A.C. or D.C., also by manual control.  vacuum circuit breaker

Applying ambient conditions:

1. The elevation should be no higher than 1000m.2. Ambient temperature: The max. temperature should be +40C. The min. temperature should be -10C.3. Relative Humidity: The average humidity of a day should be no more than 95%. The average humidity of a month should be no more than 90%.4. Saturated Vapour pressure:The average saturated vapour prereure of a day should be no more than 2.2×10-3 Mpa; The average saturated vapour prereure of a day should be no more than 1.8×10-3 MMpa.5. It should be used in the places without fire, explosion, serious filth, chemical erosion and violent vibration.
