Abstract: 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.

Abstract: An electromechanical circuit breaker comprising a main contact pair comprising a first main contact disposed on a first main contact bridge; an auxiliary contact pair comprising a first auxiliary contact disposed on a first auxiliary contact bridge, the first auxiliary contact bridge being connected in parallel to the first main contact bridge and wherein the auxiliary contact pair comprises a material that has a higher melting point than a material of the main contact pair; a first armature configured to move the first main contact bridge; a second armature configured to move the first auxiliary contact bridge, wherein the first and second armatures are configured such that the auxiliary contact pair opens after the main contact pair opens, and the auxiliary contact pair closes before the main contact pair closes.
