Abstract
An arc interruption structure for an electric switching device such as a contactor having one or more J-plates (38,42,46,48) adjacent to but insulated from each contacts gap provided by stationary contacts (20,22) and a movable bridging contact (24) of the contactor whereby sub-arcs are received from the contacts gaps to the bend (38c) of the J-plates and move therefrom along the short limb (38b) of the J-plate to the extremity (38c) thereof, thus to be retained and extinguished within the arc interruption structure and not ejected either forwardly into the vent space or reversely back toward the contacts gap. The J-plates (38,42) may have various forms such as a reduced-width bend (38c) with greater width limbs (38a,38b) or a reduced-width bend (52d) and short limb (52c) with a greater width long limb (52f). These J-plates may be used with arc runners (22a,24a) and/or with one or more flat, arc splitter-plates (40,41,44,45) and/or an auxiliary arc bridge (30 ).
