Abstract (en)
[origin: CN109961986A] The invention relates to an electrical device for establishing or breaking current in an electrical circuit. The said device comprises at least two pairs of fixed contacts (19 to 24), each pair comprising two fixed contacts of an upstream terminal (11 to 14) and a downstream terminal (15 to 18) of the device, which are respectively and electrically connected to each other; and a bridge (25 to 27)of two movable contacts, which is movable between a first position and a second position. In the first position, the bridge is electrically connected to the two fixed contacts. In the second position,the flow of current between the two fixed contacts is interrupted, wherein one pair of fixed contacts and their associated movable contacts bridge are on the line (8, 9, 10) of the transmission phase, and the other pair of fixed contacts and their associated movable contacts bridge on the line (7) of the transmission neutral. The apparatus is characterized in that the electrical connection between the two terminals (11, 15) on the neutral line (7) is a permanent connection.
