Product Description

FN3-12, FN3-12R, FN3-12R/S load to open the high voltage electrical appliances of the indoor device. Suitable for AC 50Hz, 6kV or 12kV network, as a switch to break and close load and overload current, can also be used to break and close no-load long line, no-load transformer and capacitor switch. Load switches with type RN3 fuses (FN3-12, FN3-12R/S) can cut short circuit and be used as protection switches. The load switch can be operated by CS3 type and CS2 type manual operating mechanism.
