Automotive glossary: What is a Fuse?

Fuse
Definition of Fuse: In the case of a short-circuit in a electric circuit by a defective isolation, a loose contact or likewise, the amperage can increase in such measure, that the overheating of the wiring or other conducting parts leads to a fire. To prevent such fire, fuses are installed in the circuit. Their task is to blast when the amperage suddenly increases markedly, and to cut off the circuit consequently. It is a mere fire prevention and by no means a personal protection from electric shocks. The amperage where a fuse blasts, is given on the outside in amps. There are fuses in different versions, but principally always consist of a more or less thin wire, that melts at a certain amperage.
