ZN63(VS1)-12 Indoor high voltage vacuum circuit br

Indoor high voltage vacuum circuit breaker ZN63(VS1) Introduction: Indoor high voltage vacuum circuit breaker ZN63(VS1)-12 is indoor switchgear equipment with 3phase, AC ,50(60)HZ, rated voltage 12KV. The prduction of this series shall be in conformity with GB1984,GB3309,JB3855,DL/T403 and relative IECstandard. Under normal operation and within the rated technical parameter, it can be operated in safety and reliable, at same time , it can be operated frequently with AC or DC, also it can be operated by manual. In the switch cabinet, the product can be installed by means of fixed or withdrawable installation, the main electrical circuit installation adopts the integrated solid sealed column to realize the circuit breaker with the advantages of miniaturization,high reliable and no maintenance. Working condition: The ambient temperature is not higher than +40°C and not lower than - 5°C Altitude above sea level 1000m, the high prototype does not surpass 3000m The air relative humidity daily average is not bigger than 95%, the monthly average humidity is not bigger than 90% The steam pressure daily average value does not surpass 2.2kPa, the steam pressure monthly average value does not surpass 1.8kPa, it might be air condensation when temperature drops down suddenly during the high-moisture. No pollution,anti-explosion, Serious contamination,chemical corrosion and earth quick place. The earthquake intensity is not more than 8 level.
