Use environment

 1,Surrounding air temperature:The surrounding air temperature is not lower than -5°C,is not higher than +40°C,the average value does not surpass +35°C lowest storing temperatures is -25°C. When the sur-rounding air temperature is higher than +40°C or is lower than -5°C situation consults by theuser and the factory.2,Altitude above sea level: The installation site altitude above sea level does not surpass 2000m.3,Atmospheric condition: Atmospheric relative humidity, when maximum temperature +40°C does not surpass 50%, The low temperature to be allowed to have a higher humidity, if The wet average tempera-ture is +25°C, the averge maximum relative humidity does not surpass 90%. And considers the place of dew on the products surface.4,Pollution rank: The pollution rank is 3 class in the place of using contactor.5,Installs category: The installment category of contactor is ill.6,Installs condition: The contactor according to the normal work position installment, the fitting su rface and the vertical gradient is not over ±5°,but the conta ctor which use for the mine mine shaft for thefitting surface and the vertical gradient is over 5°.
