This product complies with the GB14048.3 IEC60947-3 standard.

Normal working and installation conditions

The ambient air temperature shall not be higher than+40 ℃ and not lower than -5 ℃

The elevation 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%. Higher relative humidity can be allowed at lower temperatures, such as reaching 90% at 20 ℃. Corresponding measures should be taken for occasional condensation caused by temperature changes

The pollution level of the surrounding environment is Level 3

The switch should be installed in a place without significant shaking, shock vibration, and rain or snow invasion. The same installation location should have no explosive hazardous medium, and there should be no gas or dust in the medium that is sufficient to corrode metal and damage insulation.protective knife switches
