A32 Circuit breakers can operate in the following environmental conditions:
With M Smart Unit: -40℃ ~ 70℃;
With H Smart Unit: -20℃ ~ 70℃;
A32 Circuit breakers can operate at higher temperatures than the reference temperature 40℃,in this case,the derating coefficients
shown in the table must be applied.
A32 Circuit breakers do not undergo changes in rated performance up to 2000m.Beyond this altitude ,the derating coefficients shown in
the table must be applied.
The relative humidity does not exceed 85% at 40℃
,the monthly average maximum of relative humidity in the wettest month does not
exceed 90%.
The effect of surface condensation caused by temperature changes on product performance should be taken into consideration.
