Basic Knowledge Of Fuse

Submitted by • December 3, 2019

When the fuse is energized, the heat converted by the electrical energy causes the temperature of the meltable item to rise. When the normal working current or the allowable overload current passes, the generated heat is radiated to the surrounding environment through the meltable body and the outer casing, and the heat generated by convection, conduction, etc. is gradually balanced with the generated heat. If the generated heat is greater than the amount of heat dissipated, the excess heat gradually accumulates on the meltable item, causing the temperature of it to rise; when the temperature reaches and exceeds the melting point of the meltable item, it will be melted, blown and the current will be cut off and plays a role as a safety protection circuit.
