what is a fuse wire compared to normal wire?

Question

Can it stand for high surge current with short duration, for example the starting current in a switching power supply??

Answer 1

A fuse element is a fine piece of metal that has been designed with specific melting properties.

The elements are typically silver, copper, or tin.

Fuses come in various sizes and types. Each fuse element has Time-Current-Characteristics (TCC's). This is basically how long it will take the the fuse to react for a specified number of amps. The higher the current, the faster the fuse element will begin to melt.

It all has to do with the current flowing through the fuse element. The voltage level is irrelevant for the operation of most fuses.

While a fuse might be labeled 15 amps, it will take substantially more than 15 amps for several minutes before the fuse element begins to melt.

Distribution system fuses used by an electric utility can typically handle an inrush of four times the nameplate rating of the fuse for 1 second.

Depending on the inrush (starting) current, you may need a delayed fuse that is designed to handle abnormally high inrush currents. You will need starting inrush details of the power supply to select the proper fuse.

Answer 2

fuse wire is a thin low res wire which blows out when temp goes hisher than the value rated on it.
and if ur current value for short surge current is less than it,it will really work.
i mean u need to choose a fuse wire having high current rating than ur surge current.

Answer 3

fuse wire is a thin copper wire ( diameter depending of the voltage used)... when a high voltage current flows through it, it breaks (the circuit continuity)and protects the appliances in the circuit from high voltage.
