A fuse is sensitive to heat. Whenever there is a power surge or the unit heats excessively the filament in the fuse melts. This occurrence is the blown fuse. The fuse is designed in such a manner that it can bear the load of fixed amperes only. If the voltage increases beyond its amperage capacity, the fuse blows. Essentially, when the fuse blows, it cuts the power supply to the unit and thereby saving the unit from any further damage.
