Product Description

The rated insulation voltage is 750V, suitable for the circuit with AC 50Hz(60Hz), the rated working voltage of 690V and below, and the rated operating current up to 1250A, which will be used for distributing electrical energy. The breaker is equipped with overload and short circuit protection device, so as to protect the circuit and power equipment from damage. 

Ambient air temperature
The ambient air temperature is about +40 ºC; the ambient air temperature is below -5ºC; the average value of ambient air temperature 24h is not more than +35ºC.
Elevation: installation elevation of not more than 2000m.

Atmospheric condition:
Relative humidity of the atmosphere in the surrounding air temperature of +40ºC is less than 50%; the relative humidity at the lower temperature can be high; most of the wet month average maximum relative humidity of 90%, the monthly average minimum temperature of +25ºC and considering the temperature due to changes in product surface.
Pollution grade: grade 3.
