RE: More on (or is that moron?) fuses
Posted by neolith on May 4, 2017 at 09:20:23:
Ceramic and glass fuses will "blow" at the same current but in cases of very high over current there may be arcing across the gap allowing current to continue to flow. Ceramic fuses have silica inside that melts and blocks the arcing. They are recommended for situations that involve potential for explosion - for example, a hospital OR with anesthesia gas - or where high over current may be expected. Typically multimeters specify the use of ceramic fuses. Otherwise the characteristics of similarly rated ceramic and glass fuses are the same.
In situations where there is a high in-rush current (such as charging the power supply caps) causing nuisance blowing, a slow blow fuse is used. This can be glass or ceramic depending on the situation.
