Abstract
Current-limiting fuse comprising an electrically insulating housing with walls surrounding an interior space, with a first opening and with a second opening opposite to said first opening, and an integrally formed electrical conductor element extending from a first terminal area outside said housing, across said first opening, across said interior space, across said second opening and to a second terminal area outside said housing, wherein said conductor element comprises a melting section of reduced cross-section, said melting section being located in said interior space and being configured to melt, when a predefined maximum allowable electrical current in the conductor element is exceeded, and wherein a first sealing section of the conductor element seals said first opening and wherein a second sealing section of the conductor element seals said second opening. The invention is further directed to a method of manufacturing the current-limiting fuse.
