Abstract (en)
A current interrupter (10) wherein current is normally carried by a bus bar (12), and a portion of the bus bar (12) is segmented by a pyrotechnic charge (14) under excess current conditions. The charge (14) is detonated by a detonator (18) which is triggered by voltage across a resistive element (16) having a predetermined melting point connected in series with the bus bar (12). At the time the detonator (18) is triggered, the resistive element (16) provides sufficient resistance to trigger the detonator (18) while operating at a temperature below its melting point. A control device (20) may be employed to control current flow through the detonator (18).
