Abstract
A conventional fusible element is combined with exothermic reactive material such as PETN or a ribbon of aluminum-palladium to supply quickly released chemical energy for fast circuit interruption where the circuit-derived electrical energy available for interruption is low. An arc quenching substance preferably surrounds the fusible element. The exothermic reaction is initiated thermally or by supplementary electrical energy from a trigger circuit.
