Embodiments disclose a fuse comprising a one power lead, an explosion chamber and an isolating chamber, wherein the fuse is designed such that a power lead can be broken into at least two parts by an explosion triggered in an explosion chamber. The two parts are separated from each other in an associated isolating chamber by a respective electrically insulating partition. Embodiments disclose a method comprising a power lead, an explosion chamber and an isolating chamber, wherein an explosion is triggered in the explosion chamber so that the power lead is broken into at least two parts and bent into the isolating chamber such that at least two parts are separated from one another by an electrically insulating partition. The present disclosure can be applied to pyrotechnic fuses for vehicles and to high-voltage fuses.
