Outline SC40301 - the 12G/T630 - 12.5/16/20 outdoors high vacuum circuit breaker is the three phase ac outdoors high-voltage switch equipment, mainly uses in the 12KV rank, nominal current 630A, the nominal frequency 50HZ agricultural net, the city net, the mine, the railroad, the harbor electrical power distribution system, specially is suitable for the outdoors overhead line, the analysis and synthesis load current, the excess current, the short-circuit current, to electrical network perform handover and protection. This product is suitable for the below working condition: A. Ambient temperature -40 °C ~ +40 °C ; B. The elevation does not surpass 2000mm, above 2000mm and the user consultation; C. The wind pressure does not surpass 700Pa (to be equal to wind speed 34m/s); D. The relative humidity date mean value is not bigger than 95%, the monthly mean value is not bigger than 90% e. Air contamination degree III level; F. The surrounding air should not receive the caustic gas or the ignitable gas and so on the obvious pollution; G. Non- regular strenuous exercise; H. Should conform to the GB655386 related use situation requirement as the insulation medium silica gel.
