Summary:An electrical switching apparatus for bi-directional direct current switching and interruption includes separable contacts, an operating mechanism to open and close the contacts, and an arc chute. The arc chute includes two ferromagnetic side members each having a first side and an opposite second side, the first side of a second ferromagnetic side member facing the first side of a first ferromagnetic side member, a first permanent magnet disposed on the first side of the first side member, a second permanent magnet disposed on the first side of the second side member, and a single set of a plurality of arc splitter plates disposed between the permanent magnets. The permanent magnets are substantially smaller in size than each of the side members. The arc chute is divided into two arc chambers each of which is for a corresponding direction of DC flow through the contacts.
