Load current bearing fuse with internal switch element

摘要

The disclosure relates to a load current-bearing fuse with internal switch element. One example of the fuse includes a protective element with a first contact, a fuse element that connects the first contact with a second contact, and a protective element having a third contact that can be connected to a second potential of a supply network, but is electrically insulated from the fuse element. The fuse element is also disclosed to include a fluxing agent that has a lower fusion point that the fuse element itself. The fuse is further disclosed to include an internal switch element that monitors a protective element internally and can bring about a targeted disconnection.
