General
1. Rating: Rated voltage: 380V.
2. Rated current: 3150A, 50-60Hz   
3. Application: mainly applicable in power station, power substation industrial and mining enterprises as energy converter, distributor and controller of power, light and distribution device.
4. Standard: IEC60439-1

Working Conditions
1. Ambient air temperature: -15°C~+40°C

2. Daily average temperature: ≤35°C

3. When the actual temperature exceed the range, it should be used by reducing the capacity accordingly.
4. Transport and store temperature: -25°C~+55°C. do not exceed +70°C in short time.
5. Altitude: ≤2000m
6. Relative humidity: ≤50%, when temperature is +40°C

7. When temperature is low, larger relative humidity is allowed. when it is +20°C, relative humidity can be 90%. Since the temperature change will make out condensation.
8. Installation inclination: ≤5%
9. Applicable in the places without corrosive and flammable gas.
