Abstract

The device includes two breaking areas formed at each side of a contact bridge carrying main contacts that can be separated from fixed contacts located in the breaking areas and fixed to main conductors. The main conductors each have shaped extensions in the break areas that are configured to cooperate with shaped extensions associated with arc collection parts positioned nearby. The shaping of the extensions and the spacing therebetween encourage a particular direction of arc migration relative to arcs created when the moveable contacts carried by the contact bridge are separated from the fixed contacts. Further, arc migration control is provided in the form of magnetic fields provided in each breaking area. Each arc collection part is connected through a shunt conductor and a single direction of current flow establishing component to make a direct electrical connection to the main conductor associated with the other area.
