Fuse

A fuse with a fuse chamber and, at opposite ends of the same, a first electrical terminal and a second electrical terminal and also with at least one fuse element of electrically conducting meltable material, connecting the first electrical terminal to the second electrical terminal through the fuse chamber, and also with a triggerable quenching gas source for producing a quenching gas flow in the fuse chamber, wherein the fuse chamber has, at at least one end, a nozzle, which connects the same to an exhaust volume, and in that at least one fuse element is arranged substantially between the quenching gas source and the nozzle, wherein the quenching gas source comprises at least one compressed-gas tank connected to the fuse chamber via a valve.
