Description
GGD AC low-voltage distribution switchgear is suitable for AC 50HZ power distribution system. Rated working voltage for 3 phase switchgear is 380V.The rated working current of power users such as generators, substations, and mining enterprises is 3150A. Renovation, distribution and control of drive motors, lighting and power distribution equipment.
Normal use environment:
◆The ambient air temperature is not higher than +40℃ and not lower than -5℃. The average temperature within 24h shall not be higher than +35℃.
◆For indoor installation and use, the altitude of the place of use shall not exceed 2000m.
◆The relative humidity of the surrounding air does not exceed 50% when the highest temperature is +40℃, and a higher relative humidity is allowed at lower temperatures. (For example, 90% at +20°C) should be considered due to temperature changes that may occasionally produce condensation.
◆The inclination between the equipment and the vertical plane does not exceed 5% during installation.
◆The equipment should be installed in a place without severe vibration and impact, and in a place where the electrical components are not corroded.
◆When users have special requirements, negotiate with the manufacturer to solve them.
