Abstract
A flat fuse including two plug blades arranged next to one another in the same plane, being spaced from one another. The plug blades are fabricated from stamped sheet metal parts, the plug zones of which extend, in each case, rearwardly in a one piece construction into current-conducting straps. Between the straps, there is arranged a fuse fusion wire which is fastened to the straps. The current-conducting straps and the fusion conductor are surrounded by and enclosed in a plastic casing. The fuse fusion wire includes a copper wire with a silver sheathing, and the current-conducting straps as well as the plug blades are fabricated from brass, in which arrangement at least the current-conducting straps, but preferably also the plug blades, are superficially tinned. The fusion conductor is welded, in each case, to a flat side of the current-conducting straps.
