Abstract
A switchgear device, for breaking a bidirectional direct current in an electric line, having at least two connection terminals, and an even number of pairs of separable contacts, arc chutes associated with pairs of separable contacts, and tripping mechanisms associated with pairs of separable contacts and connected to one another by a mechanical link, each arc chute having an arc extinguishing chamber and permanent magnets for creating a polarity enabling an electric arc to be removed to an arc extinguishing chamber when current is flowing in the electric line in a predefined direction, the predefined direction being different for one half of the arc chutes.
