Abstract:
Disclosed are an arc path forming unit and a direct current relay comprising same. The arc path forming unit, according to one embodiment of the disclosure, comprises a plurality of magnet units disposed adjacent to each of fixed contacts. At least one of the plurality of magnet units disposed adjacent to each fixed contact is configured so that the side thereof facing the rest of the magnet units has a different polarity. Accordingly, an arc path is formed from each fixed contact in different directions from each other. Further, the arc path is formed so as to move away from the center part of the arc path forming unit. Accordingly, damage to components disposed in the center part may be prevented.
