General Electric Fuses

Electric fuse is a safety device installed between the electric source and electric circuit to save the components of the circuit from getting damaged. Overload conditions are being prevented by the use of electric fuses. The basic principle behind the working is that the fuse terminals are added in series with the electric circuit and electric voltage source, internally the fuse terminals are connected with a fusible metal or semiconductor alloy. When over currents happens the metal melts and the contact between the terminals of the fuse is damaged. The circuit now acts as a open circuit and devices are saved from being damaged.
