Why Do Fuses Have a Voltage Rating?
Fuses are designed to have very low resistance so that they don’t
unduly interfere with the circuits that they are protecting. This
low resistance means that the voltage drop across the fuse will be
very small. Why, then, do fuses have a voltage rating?
It’s true that fuses see small voltage during normal operation, but
the voltage rating is not relevant to normal operation. Rather, the
voltage rating tells you what the fuse can endure after it has
tripped. A blown fuse is an open circuit, and if the voltage across
this open circuit is enough to cause arcing, the fuse can’t be
relied upon.
It’s a good idea to keep an eye on voltage ratings if you’re using
tiny surface-mount fuses, such as the one shown below (note how
thin the actual fusing element is). The rating for an 0603 fuse,
for example, could be 32 V or even 24 V.
