1.overview
This series of automatic transfers switch is a high-tech product developed by our company with the latest technology. It conforms to the standards of GB14048.1, GB/T14048.11, and also conforms to the "code for fire prevention of high-rise civil buildings", "code for fire prevention of building design", "emergency lighting design guide", "code for electrical design of civil buildings" and so on.The parts and components of the products are strictly aged and screened.The finished products are electrified and stored for 72 hours continuously.Finally, they can be released from the factory after passing the loading inspection. Thus guaranteed the product reliable.
2.working conditions
2.1 Ambient air temperature: ambient air temperature ranges from -5℃ to +40℃, and the 24-hours average temperature does not exceed +35 ℃. Users should check with manufacturer when ambient air temperature above +40℃ or below -5℃ .
2.2 atmospheric humidity: when the highest temperature is +40℃, the relative humidity is not more than 50%, and the maximum monthly relative humidity is 90%, which can withstand the influence of the humid air at sea,and can allow higher at lower temperature!Relative humidity, for temperature change occasionally produced condensation should be taken special measures.
2.3 installation height: the elevation of installation site shall not exceed 2000m. For higher elevations, consult with the manufacturer to allow for reduced dielectric strength and cooling of the air.
2.4 pollution level: the environmental pollution level of the installation site is level 3.
2.5 installation category: installation category IV
2.6 installation inclination: the product shall be fixed in the cabinet with the maximum inclination of ±22.50.
2.7 arc distance: at ac 380V, arc distance is 80mm. At ac 660V, the arc distance is 100mm.
2.8 use category: AC-33IB.
