Abstract
An arc path formation unit and a direct current relay comprising same are disclosed. An arc path formation unit according to an embodiment of the present disclosure comprises a plurality of magnet parts. The plurality of magnet parts can form a magnetic field in a space inside an arc chamber to form an electromagnetic force for moving generated arc. The magnetic field formed by each magnet part forms an electromagnetic force toward the outside of the arc chamber. Electromagnetic forces formed adjacently to fixed contacts are formed in opposite directions. Therefore, the generated arc can be quickly moved to the outside and extinguished without damage to each constituent element of a direct current relay caused by the generated arc.
