Abstract:
Disclosed are an arc path formation unit and a direct current relay including same. An arc path formation unit according to an embodiment of the present invention comprises a plurality of magnet parts. One of the plurality of magnet parts is disposed on one surface of a magnet frame. The remaining magnet parts among the plurality of magnet parts are disposed on the other respective surfaces of the magnet frame. The magnet part disposed on the one surface is formed longer than the other magnet parts. Also, the magnet parts disposed on the other surface are spaced apart from each other as far as possible. Accordingly, the magnetic field formed between the magnet parts is formed such that the electromagnetic force generated in each of stationary contacts is generated in a direction away from the central region. As a result, damage to components disposed in the central region can be prevented.
