Abstract: An oil-type circuit breaker has three poles provided in a unitary tank structure, each pole comprising a pair of serially related grid structures. The grid structures are constructed by nesting a plurality of plate elements, constituting vent passages and oil pockets, within an outer cylindrical glass-filament-wound shell. The stationary contact assembly is so arranged as to have a lengthened finger, which serves as an arcing horn disposed adjacent side lateral vent openings. The vent openings are formed by molded vent elements of particular materials and having a splitter plate interposed therebetween. Additional oil pockets and a lower oil-pocket plug, having an entrance opening, assist in guiding the movable contact rod, and additionally providing considerable turbulence within the oil during the opening operation.
