The FN5-12 indoor AC high-voltage load switch (hereinafter referred to as the load switch) is suitable for use in AC 50Hz, 12kV networks, as a means of breaking load currents and closing short-circuit currents. Load switches with fuses can cut off short-circuit currents and serve as protective switches.
The load switch can be equipped with CS6-1 mobile phone operating mechanism, CS □ manual operating mechanism dedicated to this product, or CJ □ electric operating mechanism.
