Abstract
An electrical fuselink having improved surge-resistant characteristics comprises a fuse element (1) disposed in an electrically insulating enclosure (4) having all or part of the air-space within the enclosure filled with a microporous or microcellular insulating material (2) which has low intrinsic thermal conductivity and cavities or cells of a size less than the average inter-molecular collision distance of the gas, normally air, occupying its cavities or cells. The fuse element is connected between electrical leads (3) which project from the enclosure for connecting the fuselink in an electrical circuit.
