CDWNEGZ DC Disconnect Switch Operating Conditions:
1.Ambient temperature: -5℃ ~+40℃, daily average ≤35℃
Note: Isolation switch used at ambient air temperature above +40 ° C or below -5 ° C Consult with the manufacturer
2.Altitude ≤2000m
3.Electromagnetic interference: applies to environment A
4.Protection level: The isolation switch is installed in the small room of the cabinet, and the door frame is installed, and the protection level can reach IP40
5.Ambient humidity: the relative humidity of the atmosphere does not exceed 50% at the maximum ambient temperature of +40℃; Higher relative humidity is allowed at lower temperatures (e.g. 90% at 20 ° C), taking into account the condensation that occurs on the surface of the product due to temperature changes
