glass vs. ceramic fuses.

[Sarver Systems]

pros and cons for each?

I thought a fuse was a fuse. Too much current and it blows.

I would think you'd prefer a glass fuse, since you can USUALLY tell when its blown.

And ceramic fuses are more expensive.

[Ken Layton]

Ceramic fuses are used in applications where heat is involved such as microwave ovens.

[lilshawn]

the ceramic fuses are often filled with sand. if a high voltage goes high load and blows the fuse, the fuse blows and the sand stops an arc from forming.

a regular glass fuse can blow, and the resulting film left on the glass from the vaporized filament can allow the high voltage arc to strike and cause further damage.
