| Summary: | Disclosed is a direct current relay. The direct current relay according to one aspect of the present invention may comprise: an upper part cover formed with a space inside; an arc chamber accommodated in the space of the upper part cover, and accommodating a fixed contact and a movable contact applying an electric current to the outside; a magnetism generating part that surrounds the arc chamber and is accommodated in the space of the upper part cover, forming a magnetic field inside the arc chamber; and a cooling part, that surrounds the arc chamber and the magnetism generating part and is accommodated in the space of the upper part cover, configured to exchange heat with the magnetism generating part. Therefore, an objective of the present invention is to provide the direct current relay of a structure that can prevent damage to a component by heat generated together with an arc.
