An electric arc extinguishing mechanism is provided for an electric current switching apparatus of the type having a pair of contacts which selectively engage to complete an electric circuit. The mechanism includes a plurality of splitter plates located adjacent to the contacts and formed of electrically conductive material. Each splitter plate has a body of electrically conductive material, and a casing with a pair of planar portions on opposite sides of the body and connected by the curved edge portion. The edge portion is adjacent the contacts with the planar portions extending from the edge portion in an open loop having a gap. Any arc introduced between adjacent splitter plates moves around the open loop before being extinguished thereby not residing in one spot long enough to cause gross melting and associated erosion of the splitter plate.
An electric arc extinguishing mechanism comprising a plurality of splitter plates arranged side-by-side, each of the plurality of splitter plates comprises:
An electric arc extinguishing mechanism for an electric current switching apparatus of the type having first and second contacts which selectively engage each other to complete an electric circuit, said arc extinguishing mechanism comprising:
An electric arc extinguishing splitter plate comprising electrically conductive material and having two lateral portions spaced apart and connected by an edge portion, each lateral portion extending from the edge portion in an open loop having a gap.
