FUSE AND ASSOCIATED MANUFACTURING PROCESS
Fuse, comprising at least one fuse blade in which is formed a reduced section (46A) defining a plane (P4) transverse to the fuse blade. The fuse also comprises arc guards, which are made of an elastic material and which are associated in pairs, the arc guards of the same pair being each disposed opposite one another on one respective main side of the same fuse blade. Each arc guard comprises an internal face, oriented towards the fuse blade, a front face, oriented towards the reduced section, and a rear face, oriented away from the reduced section. At least one perforation is made in the fuse blade in the vicinity of the reduced section, each perforation being at least partially closed by the internal faces of the two arc guards of the same pair, each perforation leaving a cavity between the two arc guards of the same pair.
