FZ(R)N21-40.5D indoor high-voltage ac vacuum load switch-fuse combination ( "combination" for short) is used in power systems with an AC frequency of 50 Hz and a rated voltage of 40.5 kV to break load currents, overload currents and short-circuit currents. It particularly applies to the places needing control, protection for oilfree, maintenance-free, frequently-operated and ring network power supply units and terminal power supply transformers.
The combination is characterized by large breaking capacity, high safety and stability, long electrical life, support for frequent operation, less maintenance, etc. It has an apparent isolating gap, an earthing switch with making capability, an electric spring actuator and remote control capability.
