The purpose of this work is to investigate the triggering behaviour of safety fuses for mobile on board supply systems. The influence of different materials and shapes of the fuses on the triggering behaviour are analyzed. Furthermore, the simulation results obtained by the use of COMSOL Multiphysics® are compared to experimentally achieved data.

For the transient simulation of the heat distribution in the fuses, we use a system of PDEs and boundary conditions respecting convection and radiation. Good accordance of simulation and measurements for lower voltages is shown and we give a forecast on our future work concerning high voltage fuses.
