AC Low Voltage Power Distribution Board, Vacuum Circuit Breaker
Introduction - GGD AC Low Voltage Power Distribution BoardGGD AC Low Voltage Power Distribution Board applies to power generation and supply system of three-phase 50Hz AC , rated voltage is 380V, rated current is 3150A and below for the power, power distribution and lighting as well as the power transfer and control. It is widely used in power plants, substation, industrial and mining enterprises. GGD AC Low Voltage Power Distribution Board is a safe, economical and reasonable AC power distribution box which is designed by two design unions in accordance with the majority of the electricity users and the design department.
The products have high breaking capacity and dynamic thermal stability, advanced and reasonable structure, realistic programme and high universality. It can be used as the new generation low voltage series Switchgear product.
The design of this equipment meets the standards of IEC439 Low Voltage Series Switch and Control Equipment , GB7251 Low Voltage Series Switchgear and so on.
GGD AC Low Voltage Power Distribution Board of our company had passed national mandatory product identification.

Working & Environmental Conditions - GGD AC Low Voltage Power Distribution Board
1. Surrounding air temperature is lower than +40°C and is above -5°C, average temperature in 24h is lower than +35°C,
2. Indoor installation and the altitude less than 2000m relative humidity lower than 50% at +40°C, higher relative humidity is allowed if the temperature is low. E.g.: 90% at +20°C Should consider dew influence which is occasionally caused by the change of temperature.
3. The vertical angle is smaller than 5
4. The equipment should be installed in the places of no fierce vibration and impact and strong corrosion.
5. The user should consult with the manufacturer for special requirements.
