Description
The load of FN3 12, FN3 12R, FN3 12R/S is related to the high-voltage electrical appliances installed indoors. It is suitable for AC 50Hz, 6kV or 12kV network. It can be used for breaking and closing load and overload current. It can also be used as a switch for breaking and closing no-load long lines, no-load transformers and capacitors. Load switch with RN3 type fuse type (FN3 12, FN3 12R/S) cut off the short circuit for protection and shutdown.
The load switch can be equipped with CS3 type and CS2 type manual operating mechanism for operation
