Abstract: In known methods heretofore, one could generally distinguish with respect to design and tripping characteristic between the LVHBC fuse (low-voltage high-breaking-capacity fuse), which protects against overload currents, and the semiconductor protection fuse which is quick-acting in the event of a short-circuit to protect, for example, thyristors. The general-purpose converter fuse according to the present invention combines the advantages of both fuses in one unit. This is achieved by the application of fusible elements, which besides having rows of narrow sites as is customary under known methods heretofore, in addition have a row of narrow sites with comparatively long narrow sites, in whose vicinity a solder deposit is arranged. The general-purpose converter fuse simultaneously assumes the function of an LVHBC fuse and of a semiconductor protection fuse.

Abstract: A pair of metallic electrodes gripping a fusible wire are attached to opposite ends of a box-like shaped body into which is pressed a lid portion to an extent to be slightly sunken relative to an upper surface of the body.

Such a construction allows easy manufacture, enables variation of pre-arcing time-current characteristic to be kept to minimum, and brings about a high degree of reliability.

Abstract: In order to reduce the costs of assembled printed circuit boards, a printed board fuse functions with great reliability at low manufacturing costs. By coating a large area of a printed board with metal, for example, by plating, a well-defined thickness of a metal layer may be achieved in which a fuse has been separated. The well-defined thickness also allows well-defined geometry of the fuse cross-sectional area and fuse length to be achieved and therefore its resistance and interruption characteristics will also be very accurately defined. In case of a temperature rise, the metal layer surrounding the fuse will have a heat dissipating effect on the fuse, providing a substantially reduced risk of board fire.
