Abstract: A HV HRC fuse, in particular a HH full-range fuse, for a drop-out fuse system with a drop-out release mechanism has an outer fuse housing, wherein at least one melting conductor, which is wound around at least one winding body, is provided in the fuse housing. The fuse housing is at least partially open on two end faces and a contact cap designed for electrical contacting is arranged on each end face of the fuse housing. The upper contact cap is detachably connectable in a contacting position with the drop-out release mechanism and the lower contact cap is pivotally mounted on the drop-out release mechanism. Tripping of the HV HRC fuse results in tripping of the drop-out release mechanism, whereby the upper contact cap is separated from the drop-out release mechanism and the HV HRC fuse swings out from the contacting position to a swing-out position.

Abstract: The invention relates to a fuse (1), in particular SMD fuse, with an insulating housing (2) having a cavity (3), a (4) arranged in the cavity (3) of the insulating housing (2), and contact means (5) electrically connected to the melting conductor (4) for making contact with the outside of the fuse (1), wherein the insulating housing (2) comprises a base body (6) having the cavity (3) and a lid (7) closing the cavity (3) of the base body (6), wherein the contact means (5) are each arranged with an inner section (8) electrically connected to the melting conductor (4) in the interior of the insulating housing (2) and with an outer section (9) on the outer side (10) of the insulating housing (2), preferably of the base body (6).

Abstract: The invention relates to an use of a melting conductor (1) for a DC fuse (2) and a high-voltage high-power fuse (2) (HH-DC fuse), wherein the melting conductor (1) comprises an electrically conductive melting wire (3), wherein the melting wire (3) comprises at least two overload narrow sections (4) in the form of a cross-sectional constriction, wherein, preferably between the two immediately successive overload narrow sections (4) a first layer (7) comprising solder and/or surrounding the outer shell surface (6) of the melting wire (3) circumferentially at least in some areas, preferably completely, is provided in at least one first section (5), and wherein a second layer (9) surrounding the outer shell surface (6) of the melting wire (3) circumferentially at least in some areas, preferably completely, is provided adjacent to each of the overload narrow sections (4) in a respective second section (8).

Abstract: The invention relates to a use of a high-voltage high-power fuse for securing direct current transmission, wherein the direct voltage of the direct current and/or the rated voltage of the high voltage fuse (1) is greater than 4 kV.

Abstract: The invention relates to a high-voltage fuse comprising a tubular ceramic insulating member that is provided with at least one fusible element, an inner auxiliary cap which is placed on the insulating member and at least partly covers the outer surface of the insulating member in the front area of the insulating member, and an outer top cap that is placed on the auxiliary cap and at least partly covers the outer surface of the auxiliary cap. The insulating member is provided with at least one depression. The auxiliary cap is molded against the insulating member such that a positive connection to the insulating member is created in the depression. The auxiliary cap and the top cap are molded in the area of said depression in such a way that a positive connection is created.
