A fuse is an electrical component that can ensure the safe operation of a circuit. Glass tube fuses can effectively prevent molten metal from splashing on other devices and can isolate high temperatures. Generally, ordinary glass tube fuse is mostly used in electronic circuit boards with denser components. In addition, it has the characteristics of convenient and quick replacement and maintenance, and can also be applied to wires, plugs or special fuse holders. In addition, the closed fuse can also be used on equipment in explosion-proof locations.
 There are several reasons why the fuse tube chooses glass as the material.
1. The glass tube is a non-metal tube with excellent performance and is a relatively good insulating material
2. No toxic side effects, good mechanical properties, thermal stability, water resistance, alkali resistance, acid resistance, etc.
3. A wide range of applications, can be used in various fields such as chemical industry, aerospace, military, family, hospital, etc.
4. It is easy to observe the blown condition of the fuse fuse and easy to replace the fuse
5. Have good promotion value and social benefits
6. Low cost

The difference between glass tube fuse and ceramic tube fuse is that the specifications of ceramic tube fuse and glass tube fuse cannot be used in common. The overcurrent of the ceramic fuse is higher than that of the glass tube. The quartz sand in the ceramic fuse has the effect of cooling and arc extinguishing; when the current exceeds the nominal capacity, the glass tube fuse cannot replace the ceramic fuse. If the glass tube fuse is replaced by a ceramic fuse, its protection will be lost. All fuses have a thermal effect, and ceramic fuses have better heat dissipation properties, and their current is greater than that of glass tubes.

If the ceramic fuse is accidentally broken, it will not be visible to the naked eye; while the glass tube fuse can be seen; the ceramic fuse is not easy to rupture, and the glass tube fuse is easier to rupture.
