How Does a Fuse Work?
A fuse is a simple and highly effective way to protect a device from dangerous levels of current:
Current flowing through a conductor’s nonzero resistance leads to power dissipation.
Power is dissipated in the form of heat.
Heat raises the temperature of the conductor.
If the combination of current amplitude and duration is sufficient to raise the temperature above the fuse’s melting point, the fuse becomes an open circuit and current flow ceases.
Though the fundamental operation of a fuse is not complicated, there are subtle points to keep in mind. The rest of this article will help you to understand some important details related to the behavior and use of fuses.
Fuse Design Best Practices: Rated Current vs. Operating Current
It would be perfectly reasonable to assume that a fuse rated for 6 amps could be used in a circuit that might need 5 amps of steady-state current. It turns out, though, that this is not good design practice.
The current rating of a fuse is not a high-precision specification, and furthermore (as discussed above) the actual tripping current is influenced by ambient temperature. Consequently, to avoid “nuisance tripping,” you should have a fairly generous gap between your expected steady-state current and your fuse’s rated current.
