Abstract: An electrical device includes a fixed support with supply lines and a distribution circuit to supply power to a contactor block. Each contactor block includes secondary lines, each connected to a supply line, and is movable between joined and disjoined positions. Each contactor block includes a switching device for switching all secondary lines of the contactor block between open and closed. The electrical device also includes a control block, movable between joined and disjoined positions. When in the joined position, each contactor block also is held in the joined position, an electronic monitoring device of the control block also being connected to the switching device of each contactor block to control switching of each switching device independently. When the control block is in the disjoined position, the switching device of each contactor block opens the secondary lines, while each contactor block is movable between its joined and disjoined positions.

Abstract: An electrical device for supplying power to a plurality of power units comprises a fixed support and a plurality of contactor blocks. The fixed support comprises input terminals, for receiving a polyphase power current, and a distribution circuit that is configured to distribute the power current to power lines that each comprise a plurality of single-phase supply lines, the fixed support comprising a number of power lines that is the same as the number of contactor blocks of the electrical device, and each power line comprising a number of supply lines that is the same as the number of phases of the power current, each of the supply lines of a contactor block being connected to a respective phase of the power current, the supply lines being accessible on the outside of the fixed support via intermediate terminals.

Abstract: The present invention relates to a device D for controlling the poles of an electric protective apparatus capable of driving a shaft (1), called the first shaft, for supporting the movable contacts between an open position of the pole in which the movable contacts and the fixed contacts of the apparatus are separated and a closed position of the pole in which these movable and fixed contacts are closed, the said device D comprising a closure spring (2) controlled by an operating shaft (3), called the second shaft, the said spring (2) being capable of transmitting closure energy to the said shaft called the first shaft (1) after compression and passing of the said spring (2) beyond a neutral point line of passage, by means of a cam (8) rotated by the said shaft called the second shaft (3), and interacting with a roller (5) secured to the shaft called the first shaft (1), means (13) for holding the control shaft called the first shaft in the closed position, and means (18, 5) for unlocking the aforementioned ho

Abstract: A breaking device with an arc breaking shield comprising at least one stationary contact collaborating with a movable contact supported by a contact-holder arm and an actuating device of the movable contact in a casing. A movable arc breaking shield is commanded in movement to occupy a rest position and a laminating position. The movable breaking shield is connected to the contact-holder arm by an actuating rod in such a way that movement of the contact-holder arm results in movement of the movable breaking shield, the actuating rod being respectively connected to the movable breaking shield and to the contact-holder arm by a second and third pivot-pin.
