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.

Low voltage switch pole

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.
