A combined fusible element and pyrotechnic interrupter enables rapid circuit disconnection across fault levels while suppressing electrical arcs.

Side wings and guided sliding keep the firing pin aligned during conducting bar cutoff while extending the arc path for better extinguishing.

A three-electrode cut-off path diverts high-current arcs at threshold conditions while limiting fuse aging and enabling rapid opening at low current.

Hall sensors and a pyrofuse let the protection circuit handle soft and high-current DC short circuits without damaging the contactor.

A modular pyrotechnic disconnect and control architecture enables fast fault isolation while improving accessory compatibility and lowering cost.

A spring-driven fuse drawer opens a galvanically isolated auxiliary contact to confirm HVDC fuse breakage and expose dormant failures.

A conductive path or larger parasitic capacitance releases housing charge imbalances to block surge transfer while shrinking interruption circuits.

An arc chamber and pyrotechnic pusher redirect ionized gases away from busbars to prevent restrikes and back commutation in EV systems.

A two-projectile cutoff pushes the severed conductor into coolant, extinguishing arcs faster and improving circuit interruption reliability.

A moving body switches the fuse path and cuts the circuit, enabling fast interruption from low currents to high currents with arc extinguishing.

A spring-driven auxiliary contact tracks fuse breakage in a DC cut-off assembly, enabling galvanically isolated monitoring and failure detection.

A moving body first routes fault current into a fuse with arc-extinguishing material, enabling rapid arc extinction during circuit cut-off.

A three-electrode current-diverting circuit routes overload current to a fuse only above a threshold, enabling fast cut-off and longer fuse life.

A dual-projectile cutoff pushes the severed conductor into coolant to extinguish arcs faster and improve circuit interruption.

Shock-wave fracture and deionized-water arc quenching enable fast high-current interruption with adjustable multi-break voltage capacity.

A single-piece seal with multiple closed loops keeps the chamber plasma-tight around a through element, improving electric arc cut-off.

Combining a passive fuse with a pyrotechnic cutter enables overcurrent protection and immediate circuit disconnection in a compact module.

Internal sprue gating feeds molten plastic from the conductor cavity to cut overmolding distortion, weld lines, and weak arc-area joints.

A built-in disconnector monitors arrester degradation and isolates ground before failure, avoiding hot gas and arc hazards.

Combines passive fuse melting with pyrotechnic bus bar interruption to de-energize high-voltage automotive circuits during faults and collisions.

Long-fiber thermoplastic housing improves pyrotechnic switch strength, insulation, and flame resistance for compact EV overcurrent isolation.

A pyrotechnic initiator and reduced-thickness busbar break enable fast high-voltage disconnection with less arcing, weight, and space.

A fuse combines thermal fusing with actuator-driven breaking to cut small overcurrents faster and improve arc extinguishing reliability.

Combining a fuse element, pyrotechnic interrupter, and PTC path, this module de-energizes circuits quickly while limiting arcing and saving space.

A porous metal-oxide cooling body inside the interrupter quenches high-current arcs faster, limiting pressure rise and improving safety.

A busbar piece is driven into metallic filter elements so the arc is drawn away, cooled, and pressure rise is limited during current interruption.

Mechanical breaking plus thermal fusing creates multi-fracture current interruption with lower heat, fast response, and external triggering.

A cavity-extending metal filter shifts the separation arc from the busbar to a heat-dissipating element, limiting pressure rise and external effects.

A triggered fusible conductor adds rupture bottlenecks and mechanical separation to control disconnection under varying low-voltage fault currents.

A two-stage series switch disconnects high-current inductive circuits by absorbing arc energy first, then securing permanent insulation.

Serpentine labyrinth walls and narrower vent channels cool arc gases while retaining molten metal, preventing current leakage in high-voltage fuses.

A pyrotechnic disconnect switch uses gas pressure to rapidly separate contacts within an insulating medium.
