Beschreibung
Zusammenfassung:	An electric wire protection device includes a voltage adjusting unit that adjusts voltage of a power source side and supplies the resulting voltage to a load, and a controller that includes a calculation unit configured to compute temperature information of an electric wire connecting the power source and the load from a value of an electric current flowing through the voltage adjusting unit, and that is configured to make the voltage adjusting unit into a shutoff state of shutting off the power source and the load on the basis of the temperature information.
