GGD  low-voltage switchgear is widely used in power plants, substations, factories and mines, etc.. GGD  AC low-voltage switchgear complies with IEC60439 "Low-voltage switchgear and control equipment", GB7251.1 "Low-voltage switchgear and control equipment" and other standards.

Working Conditions
1.Ambient air temperature: -15℃~+40℃
Daily average temperature: ≤35℃
When the actual temperature exceed the range, it should be used by reducing the capacity accordingly.
2.Transport and store temperature: -25℃~+55℃. do not exceed +70℃ in short time.
3.Altitude: ≤2000m
4.Relative humidity: ≤50%, when temperature is +40℃ When temperature is low , larger relative humidity is allowed. when it is +20℃, relative humidity can be 90%. Since the temperature change will make out condensation.
5.Installation inclination: ≤5%
6.Applicable in the places without corrosive and flammable gas.
Note: Customized products are available
