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.
