The Fuse Wire Blowing Process: Electromagnetic And Thermodynamic Coupling.

When the current is overloaded, the fuse of device drop out fuse will generate high temperature due to resistance heating. At this time, the current not only heats the fuse but also creates an electromagnetic field around it. Especially when the current reaches the short-circuit value, the rapid change in current will generate electromagnetic force, affecting the rapid melting of the fuse. The current density distribution and fuse shape play a crucial role in the efficiency and speed of melting. Fuses are typically designed with these factors in mind to enable them to quickly disconnect the circuit when the current reaches a dangerous level, preventing circuit overload or short circuit.
