  • Publication number: 20230207238
    Abstract: A switch pole for a low voltage switching device including an insulating casing defining an internal space with a contact area and an arc extinguishing area of said switch pole, a fixed contact assembly and a movable contact assembly positioned in said contact area and including, respectively, one or more fixed contacts and one or more movable contacts, which can be mutually coupled or uncoupled, and an arc chamber positioned in said arc extinguishing area and including a plurality of parallel arc-breaking plates and a terminal arc-breaking element, which includes a plate portion arranged in parallel to said arc-breaking plates and having one or more through openings and an elongated portion protruding from said plate portion and extending across said arc-extinguishing area, from said plate portion towards said fixed contact assembly.

  • Patent number: 11688570
    Abstract: A switching device for low-voltage or medium-voltage applications including: one or more electric poles; for each electric pole, at least a fixed contact and at least a movable contact, each movable contact being reversibly movable between a coupled position, at which the movable contact is coupled with a corresponding fixed contact, and an uncoupled position, at which the movable contact is separated from the fixed contact, wherein a separation gap is present between the movable contact and the fixed contact, when the movable contact is in the uncoupled position. The switching device includes, for each electric pole, at least an arc-diverting element made of electrically insulating material.

  • Publication number: 20230122117
    Abstract: A switch system includes a mechanical switch for electrical currents. The mechanical switch operates in a conductive state and in a non-conductive state. A first actuator is configured to change the state of the mechanical switch, wherein an actuation of the first actuator is based on a Thomson coil system. A second actuator is also configured to change the state of the mechanical switch and includes a loaded spring system locked by a latch system. Each of the first and second actuators is configured to change the state of the mechanical switch depending on a property of an electrical current passing through the mechanical switch.

  • Publication number: 20230091491
    Abstract: A switch system includes a mechanical switch for switching electrical currents, the mechanical switch operating in one of a closed state and an open state; the system further including an actuator configured to change the state of the mechanical switch, wherein the actuator comprises a Thomson-coil system including a Thomson coil, and wherein the mechanical switch and the Thomson coil are electrically connected in series.
