This series of products are mainly used in low-voltage distribution equipment for infrequent manual connection, disconnection and isolation of power supply.
This product conforms to GB/T14048.3 IEC60947-3 standard.
The ambient air temperature is not higher than +40 ℃ and not lower than -5 ℃.
The altitude of the installation site shall not exceed 2000m.
Humidity: when the maximum temperature is +40 ℃, the relative humidity of the air does not exceed 50%. At a lower temperature, a higher relative humidity can be allowed, such as 90% at 20 ℃. Corresponding measures should be taken for the occasional condensation due to temperature changes.Open knife switch
