ASD25DC air switch disconnector can operate in -40 ℃ ~ 70 ℃ environmental conditions.
ASD25DC air switch disconnector can operate at higher temperatures than the reference temperature 40 ℃ ,in this case,the derating
coefficients shown in the table must be applied.
ASD25DC air switch disconnector 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.
*Configuration C for ungrounded system only
*Configuration D for either grounded or ungrounded in PV system
