  • Patent number: 10410810
    Abstract: A switching device for LV electric installations is disclosed which can include an outer casing and one or more electric poles. Each electric pole can include one or more mobile contacts and one or more fixed contacts adapted to be coupled or uncoupled. A mobile contact assembly is operatively coupled with the mobile contacts such that the mobile contacts move together with the mobile contact assembly. The mobile contact assembly is adapted to reversibly move between a first contact position, in which the movable contacts and the fixed contacts are coupled and a second contact position, in which the movable contacts and the fixed contacts are uncoupled. A mechanical control assembly is provided for operating said mobile contact assembly.

  • Patent number: 7045733
    Abstract: Described herein is a low-voltage circuit-breaker, which comprises at least one mobile contact and a corresponding fixed contact, and a positive-opening-operation device. The positive-opening-operation device in turn comprises: a moving element associated to the mobile contact; a first kinematic chain, operatively associated to said mobile contact and to an actuating device; and a second kinematic chain, associated to said moving element and to said first kinematic chain. A first lever is associated to the first kinematic chain and a second lever is associated to the second kinematic chain, said first and second levers interacting with one another during the opening operation and being equipped with blocking devices in the event of welding of the contacts together.
