Overview
WHKQ9 series automatic transfer switch appliances are suitable for double-circuit power supply systems (power grid-power grid or power grid-generator) with AC 50Hz, rated insulation voltage 1000V, rated working voltage to 400V, and rated working current 100A ~ 6300A. The power supply is switched due to abnormalities to ensure the continuous and reliable operation of important loads (such as fire protection).

Normal use conditions and installation conditions
Ambient air temperature: the upper limit is not more than + 40 ℃, the lower limit is not less than-5 ℃, and the average temperature value within 24 hours is not more than + 35 ℃.
Altitude: The altitude of the installation site shall not exceed 2000m.
Atmospheric conditions: The air should be clear and clean. When the highest temperature is + 40 ℃, the relative humidity of the air should not exceed 50%. Higher relative humidity can be allowed at lower temperatures. For example, the humidity can reach 90% at + 20 ℃. Special measures should be taken for occasional condensation due to temperature changes.
Do not use and store in the area of sulfide gas, ammonia sulfate gas and corrosive gas.
Storage Temperature: Max + 60 ℃, min-20 ℃.
Pollution Level: 3
Special usage environment: In these usage environments where the ambient temperature exceeds + 40 °C or is lower than-5 °C, the altitude exceeds 2000m, and the atmospheric environment is relatively harsh (beyond the range of the above atmospheric conditions), we can specially supply this product according to the actual working conditions of users to meet user needs.
