Product Description
General introduction
NAL load break switch and NALF load break switch-fuse combination, are high voltage and high performance load break switch that combines gas pressure arc extinguishing and gas generation arc extinguishing. So far, more than 600,000 units have been installed and put into use around the world.
NALF load break switch- fuse combination has the advantages of load break switch and fuse. Load break switch can break any load current up to its rated breaking current. The fuse and its impact device break
any overcurrent up to the rated short circuit breaking current.
Applications:
The main areas of application of NAL/NALF switch-disconnectors are as:
- Line and transformer switch in medium voltage power distribution system
- Electrical motor switch
- Capacitor switch
