Patent number: 11764551Abstract: A multipolar electrical protection system including a plurality of devices for switching an electric current. Each switching device has a plurality of compartments each comprising an extinguishing chamber and a pair of separable electrical contacts that are connected to upstream and downstream connection terminals, the separable electrical contacts being movable between open and closed positions under the action of a tripping device. The switching devices are separate from one another, while the upstream terminals of each device are connected by a first connector in order to keep them at one and the same electrical potential and the downstream terminals of each device are connected by a second connector in order to keep them at one and the same electrical potential. The switching devices are controlled by one and the same common tripping device.Type: GrantFiled: December 15, 2020Date of Patent: September 19, 2023Assignee: Schneider Electric Industries SASInventors: Marc Rival, Cyril Domenech, Stéphane Dye, Daniel Rota

Patent number: 6265957Abstract: An electromagnetic actuator comprises a fixed magnetic circuit made of ferromagnetic material and a movable assembly designed to slide axially between a rest position and an active position. Two return springs bias the movable assembly to its rest position, the second spring having a greater stiffness than the first one. An excitation circuit generates a magnetic flux which is designed, in inrush mode, to move the movable assembly from its rest position to its active position and, in holding mode, is sufficient to hold the movable assembly in the active position. In a first part of the axial travel of the movable assembly from its rest position to its active position, the action of the first spring is preponderant, whereas in the remaining travel up to the active position, the action of the second spring is preponderant.Type: GrantFiled: July 26, 2000Date of Patent: July 24, 2001Assignee: Square D CompanyInventors: Pierre Baginski, Daniel Rota
