GGD Series AC Low-Voltage Power Distribution Cabinet
The GGD series AC low-voltage power distribution cabinets are suitable for use in power plants, substations, industrial enterprises, and other facilities. They are designed for the conversion, distribution, and control of electrical energy for power, lighting, and distribution equipment within AC power distribution systems featuring a frequency of 50 Hz, a rated operating voltage of 380 V, and a rated current of up to 3150 A.
Product Details
The GGD series AC low-voltage switchgear is suitable for power plants, substations, industrial enterprises, and other power users for power conversion, distribution, and control of power, lighting, and distribution equipment in AC 50Hz power distribution systems with a rated operating voltage of 380V and a rated current up to 3150A.
This product features high breaking capacity, with a rated short-time withstand current of up to 50KA. It offers flexible circuit design, convenient combination, strong practicality, and a novel structure, making it a suitable replacement for existing low-voltage switchgear assemblies.
The product complies with IEC 439 "Low-voltage switchgear and controlgear assemblies" and GB 7251 "Low-voltage switchgear assemblies" standards.
Normal Operating Conditions
Ambient air temperature: Maximum +40°C, Minimum -5°C; Average temperature over 24 hours must not exceed +35°C;
Ambient air relative humidity: Not exceeding 50% at the maximum temperature of +40°C. Higher relative humidity is permissible at lower temperatures, such as 90% at +20°C. The potential for occasional condensation due to temperature changes should be considered; Altitude: Indoor installation location must not exceed 2000m.
The tilt angle between the device and the vertical machine should not exceed 5°; the device should be installed in a location free from severe vibration and impact, and where electrical components are not subject to undue corrosion; For special requirements from the user, please consult with our company.
