WHAT SPECIFIC ADVANTAGES DO FUSELINKS HAVE?

Fuselinks have many unique performance characteristics:

Optimum Component Protection
They reduce short circuit currents that flow to a low value by "current limitation". There is no need for complex short circuit calculations and no concerns about costly future upgrades due to system expansion with increased fault currents. Their compact size offers low cost overcurrent protection for the highest short circuit levels.

Safety
No emission of gas, flames, arcs or other materials when clearing any value of overcurrent up to the highest level of short circuit. In addition, the speed of operation on high short circuit currents limits significantly the flash hazard at the fault location.

Reliability
No moving parts to wear out or become contaminated by dust, oil or corrosion and no nuisance tripping.
If a fault occurs, the fuselink immediately operates in its predetermined manner or co-ordinates with other circuit components. The cause of the fault is then ascertained, corrected and a new fuselink fitted. Fuse replacement ensures protection is restored to its original state of integrity. It should be stressed that the time taken for the replacement is very small in relation to the fault correction.

Simple Co-ordination
Standardised fuselink characteristics and a high degree of current limitation ensure that there is simple and effective co-ordination between fuselinks and with other devices.
