Fuses
Wire Fuse
Features
An improved version of overcurrent protection fuse that is used in low pressure inlet line, as the demand for reliability of electric supply equipment increases
- It is completely sealed, and hence does not suffer from thermochemical reaction of usable body due to external elements
- Terminal portion is completely sealed, which makes it safe
- It’s cramp-connected with electric wires. This makes installation simple and sturdy.
- Fusing characteristic is suitable for overcurrent protection in inlet line.
- There is no emission of toxic gases when interruption of high current.
