  • Patent number: 4523172
    Abstract: A high voltage quick-break fuse has at least one silver fuse element and at least one tin fuse element in series connection. It is a full-range fuse dimensioned in such a way that, even in the case of critical overcurrents where hitherto fuses have had a tendency to explode, the in each case appropriate fuse element system comes into action, before the fuse can explode as a result of the rising internal pressure. Further developments relate to the housing of particularly thin silicone sleeves, supported by a fabric, in fuse tubes according to the DIN standard.
