3. Application

FN7-12DR series AC high voltage load switch is a kind of new gas-type indoor high voltage load switch, applied to AC 50Hz and rated voltage 10KV for three-phase AC power system. It is used as the breaking load current and closing short-circuit current. Following part are some parameters about environment. The max ambient air temperature is 40 ℃. The mix ambient air temperature is 10 ℃for the general area and -25 ℃ for the alpine region. The daily average relative humidity is less than 95% in area of altitude less than 2000m and the month average relative humidity is less than 90%. The ambient air should not be obviously polluted by corrosive or flammable gases and water vapor. No recurrent severe vibration.
