FZW28-12 Directional Responsibility Boundary Vacuum Load Switch
FZW28-12 Directional Responsibility Boundary Vacuum Load Switch (hereinafter referred to as "Watchdog") is used in a three-phase power system with AC 50Hz and rated voltage 12kV, as the load current, overload current and short-circuit current in the split and combined power system Used. After the load switch is equipped with a watchdog controller, it can identify current characteristics and realize rapid processing of faults in the responsibility area or permanent fault isolation; minimize the impact on other users.
