摘要： A direct current arc chute (200) includes a ferromagnetic base (202) having first and second ends (204,206); first and second ferromagnetic side members (208,210) disposed from the respective first and second ends; a third ferromagnetic member (212) disposed from the base intermediate the side members and having an end portion (214) opposite the base; and first and second magnets (216,218) on the respective first and second members have a magnetic polarity facing the third member. A first arc chamber (220) is between the first and third members; and a second arc chamber (224) is between the second and third members. The first magnet and first member extend away from the first end and beyond the end portion, and toward the second magnet and second member after the end portion. The second magnet and second member extend away from the second end and beyond the end portion, and toward the first magnet and first member after the end portion.
