How long do fuses last?

How long does a fuse last? If the fuse does not operate then it will typically last 20 - 30 years as long as it is operating within its design limitations. If it is in a higher cyclic operating temperature i.e. very cold or very hot, then this can reduce its life.

Do fuses deteriorate over time?

Fuses degrade with time and will eventually fail. A blown fuse does not always mean that there is something wrong with the equipment, and in this article we will show you how to replace such a fuse. However, do not keep replacing a fuse if it blows immediately after you replace it.
