Abstract (en)
[origin: WO2017103036A1] The invention relates to a load current-carrying fuse comprising an internal switching element having a protective element (F), wherein the protective element (F) has a first connection (FA1) for connection to a first potential (L) of a supply system and has a second connection (FA2) which can be connected to a second potential (N) of the supply system by means of a device (Z) to be protected, wherein the protective element (F) has a fusible conductor (D) which connects the first connection (FA1) and the second connection (FA2) of the protective element (F), wherein the protective element (F) further has a third connection (FA3) which can be connected to the second potential (N) of the supply system and which is arranged adjacent to, but electrically insulated from, the fusible conductor (D), wherein the fusible conductor (D) has a constriction (E) in the region of the adjacent connection (FA3), wherein the constriction is designed such that the fusible conductor (D) has an electrically conductive fusible means (SM) in the region of the constriction (E), wherein the fusible means (SM) has a lower fusion point than the fusible conductor (D) itself, wherein the load current-carrying fuse further has an internal switching element which internally monitors the protective element (F) and can implement targeted disconnection, wherein the internal switching element has a voltage-sensitive element (TVS) which is connected to the first connection (FA1) by way of a connection, and which is arranged adjacent to a further connection of the overvoltage-sensitive element (TVS) but electrically insulated from the fusible conductor (D) and adjacent to, but electrically insulated from, the third connection (FA3).
