What is Fuse?

The fuses are devices consisting of a conductive material, called a fusion link, surrounded by an insulating material body, connected to two contacts that facilitate its connection with the components of the installations. The main function of fuses is to protect electrical installations against the effects of short-circuit currents or overloads. Its electrical contacts are usually made of silver brass or copper in order to avoid oxidation and occurrence of bad contact, which generate heating that damages the proper functioning of the system. Its body is made of insulation material and good mechanical resistance, which does not absorb moisture, usually ceramic, porcelain or soapstone (material with insulating characteristics superior to porcelain).
