    Abstract: A protection system configured to protect plural DC voltage sources configured to be connected in parallel between first and second input terminals of a voltage inverter. The voltage inverter can convert a DC input voltage into an AC output voltage. Each DC voltage source is connected by a first electrical conductor to the first input terminal and by a second electrical conductor to the second input terminal. The protection system includes: for each DC voltage source, a first cut-off member and first detector of a defect of isolation of the first conductor with respect to an electrical ground, the first detector and associated first cut-off member connected in series between the corresponding DC voltage source and the first input terminal of the inverter; and a mechanism triggering, in event of detection of the isolation defect, the associated first cut-off member to open the electrical link corresponding to the first conductor.

    Abstract: An electrical protection device capable of operating without auxiliary electrical power supply includes a control module configured to detect an electrical fault and a switching module, a first circuit including at least two normally-on JFET transistors and a switching member including a first contact. The switching module is configured so that, upon a switchover of the first contact when the current circuits, an electric arc is formed and so that the appearance of the electric arc generates an electrical signal transmitted to at least one of the transistors, the electrical signal driving the switching of the transistor.

    Abstract: This limiter pole (B) for a multipole DC electrical switch (2) comprises a compartment in which an input terminal and an output terminal for a direct electric current are provided, along with a first electrical contact connected to the input terminal and a second electrical contact connected to the output terminal, third and fourth electrical contacts connected to one another in series, the third and fourth contacts being capable of being moved simultaneously relative to the first and second electrical contacts, respectively, between a closed position, in which the first and third contacts and the second and fourth contacts make contact with one another so as to allow the direct electric current to flow between the input terminal and the output terminal, and an open position, in which said contacts are located away from one another, interrupting the flow of the current between the input terminal and the output terminal. The limiter pole (B) comprises a first electric arc formation chamber in which the first and third electrical contacts are placed, a second electric arc formation chamber in which the second and fourth electrical contacts are placed, and first and second electric arc extinguishing chambers which are associated with the first and second electric arc formation chambers, respectively.

    Abstract: A DC electrical circuit breaker includes first and second movable electrical contacts. The circuit breaker includes a magnetic circuit including a magnet and generating a magnetic field able to guide an electrical arc in the direction of a quenching chamber, and having for this purpose curved field lines extending perpendicularly to opposite lateral walls of an electrical arc formation chamber, these field lines converging, in a central region of the arc formation chamber containing the contact zones, toward the quenching chamber while extending parallel to the longitudinal plane.
