NGC drop-out fuses are gas-jet type distribution network fuses, which provide excellent fault current or over-voltage protection in transformers, capacitors, cables and lines in the functional switch system.
This type of drop-out fuse is made up of superior ceramics insulators and finely machined parts. It has beautiful appearance, reasonable structure, safety and reliability, and is easy to use.
