GGD AC low-voltage switchgear is suitable for power distribution systems with AC 50Hz, rated working voltage of 380V, and rated working current of up to 3150A in power plants, substations, factories and mining enterprises, for the purpose of energy conversion, distribution, and control of power, lighting and distribution equipment.
GGD AC low-voltage switchgear is a new type of AC low-voltage switchgear designed according to the requirements of the Energy Department's superiors, large power users and design departments, based on the principles of safety, economy, rationality and reliability. The product features high breaking capacity, good dynamic and thermal stability, flexible electrical schemes, convenient combination, strong practicality, novel structure, and protection level, and can be used as an updated product for complete sets of low-voltage switchgear.
GGD AC low-voltage switchgear also meets standards such as IEC439 "Complete Low-voltage Switchgear and Controlgear" and GB7251 "Low-voltage Complete Switchgear."
Surrounding air temperature should not exceed +40℃ and not be lower than -5℃, and the average temperature within 24 hours should not exceed +35℃;
Indoor installation is recommended, and the altitude of the place of use should not exceed 2000m, which should be specified when ordering;
The relative humidity of the surrounding air should not exceed 50% at a maximum temperature of +40℃, and a higher relative humidity (e.g. 90% at +20℃) is allowed at lower temperatures to consider the possible effect of condensation caused by changes in temperature;
When installed, the incline from the vertical surface should not exceed 5°;
The equipment should be installed in places where there is no severe vibration or shock and that are not likely to cause corrosion of electrical components;
Customers can negotiate with the manufacturer to meet specific requirements.
