FIELD: electricity.
SUBSTANCE: invention relates to a direct current contactor with a preferred direction of current flow, having double interruption with two contact points, each of which comprises a fixed contact and a movable contact, wherein movable contacts are arranged on a contact bridge. Direct-current contactor comprises an arc-quenching device for electric arc quenching, as well as a device for blowing configured to blow switching arc, formed in first contact point when contact points open, into arc-quenching device for electric arc quenching, when switching to first direction of current. Near movable contact of first contact point there is a switching plate, contact bridge and switching plate are electrically insulated from each other and switching plate is connected by potential to fixed contact of second contact point.
EFFECT: improved switching.
