FN3-10, FN3-10R, FN3-10R/S load switch

/Load switch purpose
/Load switch connects high-voltage electrical appliances installed indoors. It is suitable for AC or high-voltage networks to break and close loads and overload currents. It can also be used to break and close no-load long lines. Switching of no-load transformers and capacitors. The load switch with type fuse can cut off the short circuit and serve as a protective switch.
This load switch can be operated with type and type manual operating mechanisms.
Two working conditions
This load switch is suitable for the following working environments
The altitude does not exceed meters
The ambient air temperature is not higher than ℃ and not lower than ℃
The relative humidity of the air In an indoor place no larger than 100 ℃ when the temperature is ℃
In an environment without conductive dust
Without corrosive gas objects that damage metal and insulation
A place without severe vibration and impact
In an environment without danger of combustion and explosion.
