A fuse sub-assembly has a hollow cylindrical support body 1 of an insulating material. A multiplicity of elongate conductors 2 extend helically around the outer surface of the support body 1 and merge at each end of the support body 1 into a conductive band 5, 6 provided around the circumference of the support body 1. The conductors 2 are of a fusible material, with groups of adjacent conductors 2 being merged together at at least one intermediate region along their lengths to form a bridge 8. The bridges 8 significantly improve the full-range performance of the fuse sub-assembly. |
