Patent number: 11437200Abstract: A low voltage contact assembly including a rotating support having a body adapted to rotate around a rotation axis and supporting at least a first couple of movable contacts that can be coupled to/uncoupled from corresponding first fixed contacts by rotation around said rotation axis. The first couple of movable contacts include a first and a second movable contacts housed in the rotating support. The low voltage assembly further includes a pressure exerting device having a pressing bar operatively coupled to the first and second elongated contact body and transversally placed with respect to the rotation plane of the first and second elongated contact bodies.Type: GrantFiled: May 29, 2020Date of Patent: September 6, 2022Assignee: ABB S.P.A.Inventors: Marco Bonfanti, Mauro Ghislotti, Michele Ceroni

Patent number: 10510472Abstract: The present application relates to a coil actuator for low and medium voltage applications, which comprises a electromagnet operatively associated with a movable plunger, a power & control unit electrically connected with the electromagnet and first and second input terminals (T1, T2) operatively connected with the power & control unit, wherein an input voltage (VIN) is applied between said first and second input terminals during the operation of the coil actuator. The coil actuator further comprise a third input terminal (T3) operatively connected with the power & control unit, the third input, terminal being adapted to be in a first operating connection (A), which correspondences to normal control conditions (NDC) for the operation of the electromagnet, or in a second operating condition (B), which corresponds to overriding control conditions (ODC) for the operation of said electromagnet.Type: GrantFiled: March 12, 2017Date of Patent: December 17, 2019Assignee: ABB S.p.A.Inventors: Davide Pessina, Mauro Ghislotti

Patent number: 10410810Abstract: 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.Type: GrantFiled: February 8, 2017Date of Patent: September 10, 2019Assignee: ABB S.P.A.Inventors: Roberto Rota Martir, Mauro Ghislotti
