Why Fuses Blow & Circuit Breakers Trip Fuses and Circuit Breakers are safety devices designed and installed in electrical circuits TO PROTECT the conductors [wires] from short circuits and overload conditions which can cause extreme overheating that can result in damage to the insulation and the conductors and worse, the possibility of a FIRE which could destroy the vehicle. When a fuse, and replacement fuses, blows, especially if it happens repeatedly, is an indicator of an UNSAFE CONDITION in that circuit, usually a short. Do not install a larger fuse in a misguided attempt to correct the problem. To install a larger fuse would almost guarantee damage to the wiring and an electrical system fire. The proper "fix" is for a qualified technician, who knows what he/she is doing, to troubleshoot the circuit, find and identify the defect, and make proper repair [s], BEFORE replacing the fuse again [with the properly sized fuse].

A: FUSES are very good for short circuit protection. On the other hand a short over current may not make the fuse to blow since it requires heat caused by the current to blow. There are fuses that are meant to blow fast and some fuses are designed to blow slow depending on the circuit requirement
