Definitions

  • This object is accomplished according to the invention by providing a fuse wherein the substantially cylindrical housing comprises a central, substantially cylindrical portion, which central portion, at opposite ends thereof in the vicinity of, but spaced away from said ends, merges with an end portion of an at least initially greater outer diameter than the diameter of the central portion, which end portion of said at least initially greater diameter has, in the direction of the end, a first portion which is of cylindrical configuration or forms an outward ridge and a remaining portion of substantially conical configuration.
  • Suitable materials which can be used for the housing 1, the end caps 10 and 11 and the fuse element 7 are the same materials as those mentioned in the above-mentioned European Patent Application 0,199,401, and others.
