Applicable scope
The HD11F and HS11F series single throw and double throw protective knife switches are newly developed products derived from HD11 and HS11 by our company.
They are ideal substitutes for HD11 and HS11, greatly improving personal safety protection performance and preventing accidental electric shock.
This series of products is mainly used in low-voltage distribution equipment for infrequent manual connection, disconnection, and isolation of power supply.
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
