Conditions of Use
>Normal use conditions
>Ambient temperature-25°C~+40°C
> Altitude: no more than 2000m
> Humidity conditions: the average relative humidity does not exceed 95%, the averagemonthly relative humidity does not exceed 90%, the average daily water vapor pressure doesnot exceed 2.2kPa, and the average monthly water vapor pressure
Not more than 1.8kPa
> The surrounding air is not significantly polluted by dust, smoke, corrosive and/or flammablegases, steam or salt mist
> Vibration or ground motion from outside of switchgear and control equipment is negligible> The amplitude of electromagnetic interference induced in the secondary system shall notexceed 1.6kV.
> Special Conditions of Use
According to the national standard GB/T11022-1999,"Common technical requirements forhigh-voltage switchgear and control equipment standards", the circuit breaker should operateunder normal conditions of use. lf the working conditions used by the user are different fromthe normal use conditions, such as: the installation site is at an altitude of more than 2000m.the ambient air temperature exceeds the limit specified in the normal use conditions, or thehigh humidity is prone to condensation, it should be negotiated with the manufacturer, and reached consensus.
