Abstract
An oil filled capacitor has an exothermically alloyable fuse strand within the closed housing that is filled with a dielectric oil. A circuit interruptor means is included within the housing that interrupts a capacitor section to housing terminal connection either in response to overpressure or to overtemperature within the housing, or both. The fuse strand is part of that connection and a portion of the fuse is located at the predetermined point of potential interruption so that any arcing that occurs across the gap of the opened connection will kindle the fuse which in turn will be completely obliterated and quench the arc.
