Slow-Blow Fuse vs Fast-Blow Fuse
There are various types of fuses: a slow-blow fuse, a fast-blow fuse, and a two-blade mini fuse. In today’s market, we find a fuse for every electronic need. If you are a beginner or you don’t have any experience whatsoever in electrical work, then you have to learn to distinguish among different types of fuses. Otherwise, you will eventually damage electronic equipment by installing an improper fuse. Therefore, it is always recommended that you install the same type of fuse originally used for a particular electronic circuit to prevent problems. Follow this guide to better understand the differences and common usages that exist between a slow-blow fuse and a fast-blow fuse.
The Definition of a Slow-Blow Fuse and a Fast-Blow Fuse
A slow-blow fuse is defined as a fuse that can tolerate high levels of voltage for a short period without shorting itself. This means that when a short or a sudden change in voltage occurs, a slow-blow fuse doesn’t burn immediately but withstands the high current for a short time, giving you the time to do what you were going to do or time to turn off the power source.
On the contrary, a fast-(or quick)blow fuse is a fuse that bursts instantly when high power voltage is passed through it. This fuse is the common fuse we find in much everyday electronic equipment.
