Abstract
A mechanical breaker apparatus for breaking an electric circuit comprises two electrodes that are movable relative to each other, and including an electric arc splitter device having a multitude of distinct conductive elements that are spaced apart and electrically insulated relative to one another. The splitter device has a first portion and a second portion that are movable relative to each other between: an electrical contact position; and a spaced-apart position of the two portions. The splitter device has at least one series of the distinct conductive elements that, in an electrically closed position of the electrodes of the mechanical apparatus, are arranged along the continuous electrically-conductive path for the nominal electric current through the apparatus as defined by the two portions of the splitter device in the electrical contact position.
