ELECTRIC FUSE HAVING LARGE CYCLING ABILITY AND GAS-EVOLVING MEANS Abstract of Disclosure A fuse having a high cycling ability combined with a high arc-extinguishing ability due to the presence of a gas-evolving material. The fuse includes a pair of fusible elements having end portions and intermediate portions arranged between the end portions and converging in opposite directions, so as to form a pair of wedge-like structures. The pair of fusible elements is composed of planar portions and portions where these planar portions meet. The fusible element has points of minimized cross-section which are spaced from any bent in the fusible element. The improvement comprises a rectangular plate of gas-evolving material inserted into the gap, or space, defined by the pair of parallel fusible elements. The terminal elements of the fuse and its casing form abutments for the plate of gas-evolving material in longitudinal and in transverse direction so that no additional means are required for maintaining the gas-evolving plate in position relative to the pair of fusible elements of the fuse. -1-
