The combination device high-voltage load switch - AC fuse type FKRN12-12D/T125-31.5 is a high-voltage switching device for indoor installation, which is a combination of load switch FN12-12D and high-voltage current-limiting fuse type S ☐ LAJ-12 (XRNT ☐ -10).
High-voltage load switch for indoor AC installation type FKN12-12D/T630-20 (hereinafter referred to as “load switch FKN12-12D”) is a three-phase high-voltage switching device with a rated voltage of 12 kV, a rated frequency of 50 (60) Hz, designed to switch on and off load currents, closed-loop currents, no-load currents of transformers and charging currents of cables, as well as for switching on short-circuit currents. A load switch equipped with an earthing switch is capable of withstanding short-circuit currents.
