The present invention relates to an electrical fuse element having an essentially ceramic housing which, in the unfired state, is closed around at least one fusible conductor. To improve the properties of such a fuse element with respect to the extremely high internal pressures occurring during switching off as well as when exposed to an arc, a fuse element ( ) in which the fusible conductor ( ) has an electrically conducting component, in particular a metallic wire ( ), and an insulating, porous component is proposed.

Electrical fuse element

An electrical fuse element ( ), which comprises a substrate ( ) with two contacts ( ) arranged on opposite end sides ( ), terminal areas ( ) connected to the contacts and a fusible conductor ( ) electrically connected in a conducting manner to the contacts via the terminal areas, is developed for use in higher voltage ranges, with improved breaking capacity and with low production costs, by the terminal areas ( ) and the fusible conductor ( ) being arranged separated from one another by an insulator ( ) and electrically connected to one another via lead-throughs.
