Indoor Long Electrical Life AC 10KV High Voltage Vacuum Load Break Switch
FZ(R)N2 1-12D indoor high-voltage alternatin-current 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 10 kV to break load currents, overload currents and short-circuit currents. It particulaly applies to the places needing control, protection for oilfree maintenance-free and frequently-operated ring network power supply units and terminal power supply transformers.
The combination is charaterized 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.
