20110068884 | Electromechanical actuator - The present invention is directed to an inductively driven electromagnetic linear actuator arrangement employing eddy currents induced in an armature by a drive coil to drive the armature. Eddy current focusing fields (Lorentz force) are employed to direct the induced eddy currents to maximize armature speed. The armature includes a shorted driven coil in a DC magnetic field that focuses eddy currents induced by the drive coil in the driven coil. The DC magnetic field can be supplied by one or more permanent magnets. When current is applied to the drive coil, a force is felt by the driven coil in a direction perpendicular to the magnetic field, causing armature movement. Such an actuator is well suited for electrical switching applications including transfer switching applications, circuit breaker applications, and ground fault interrupter applications. | 03-24-2011 |
335102000 | Polyphase | 2 |
20130120092 | MULTIPOLAR ELECTRICAL SWITCH - A multipolar electrical switch includes at least one central pole housing, which adjoins two adjacent pole housings of the switch. In at least one embodiment of the invention, an electrical switching mechanism for switching an electrical phase current on and off is contained in each of the pole housings respectively. The central pole housing is equipped with a fastening element, which extends through the central pole housing into the two adjacent pole housings, namely in each instance to at most the center of the adjacent pole housings. | 05-16-2013 |

335103000 | With plural magnetic-actuating structures | 2 |
20150145621 | ELECTRICAL CONTACTOR - An electrical contactor has a first terminal having a fixed member with at least one fixed electrical contact, a second terminal, and a busbar connected to the second terminal. Two conductive movable arms are connected to the busbar and have a contact thereon. One arm is biased-closed to contact the fixed electrical contact in the absence of a separating force, and the other arm is biased-open to be spaced away from the fixed electrical contact in the absence of a closing force. The first and second movable arms and the busbar are arranged so that, when the contacts close, contra-flowing current urges the movable arms towards the fixed member to increase a force between the contacts. | 05-28-2015 |
