Patent number: 8681466Abstract: A system comprising a magnetic actuator, a current transformer and operational electronics in a dual-coil circuit breaker. The system includes an inline, but non concentric, implementation of the primary and secondary coils to maintain a narrow width suitable for retrofitting in standard industrial rack mounted enclosures. The system further comprises an I-shaped lamination stack that is designed to abut on the ends of an upper and lower plate of the current transformer. The I-shaped lamination stack significantly increases the overlap between the lamination and the upper and lower plates, which results in lower magnetic reluctance and improves magnetic coupling.Type: GrantFiled: June 17, 2011Date of Patent: March 25, 2014Assignee: Rockwell Automation Technologies, Inc.Inventors: Jeffrey Annis, Hans Weichert, Pascal Benz, Sandro Liberto, Beat Villiger

Patent number: 8456782Abstract: A system comprising a magnetic actuator, a current transformer and operational electronics in a dual-coil circuit breaker. The system includes an inline, but non concentric, implementation of the primary and secondary coils to maintain a narrow width suitable for retrofitting in standard industrial rack mounted enclosures. The system further comprises a split core design that is integrated into an upper and lower plate which slide together and are retained by a secondary coil bobbin. Typically, the two parts of the split core can be manufactured into net shapes by utilizing a powder metal or metal injection molding process. Moreover, the split core design disclosed herein can reduce costs and time associated with manufacturing and assembly of the current transformer.Type: GrantFiled: July 7, 2011Date of Patent: June 4, 2013Assignee: Rockwell Automation Technologies, Inc.Inventors: Jeffrey Annis, Hans Weichert, Sandro Liberto, Beat Villiger

Patent number: 6767242Abstract: A terminal covering cap is mounted over the connection terminals of a multi-phase electrical switching device in order to increase the electric strength between the connection terminals of neighbouring phases. The L-shaped terminal covering cap closely abuts on its side facing the insulating housing the marginal region of connection openings leading to the connection terminals, with a negligible air gap. With this barrier, the required increased test voltage between the connection terminals can be withstood. On the side facing away from the insulating housing, the terminal covering cap is provided with ribs, to extend the creep distance on this side of the terminal covering cap. The terminal covering cap formed in this way makes it possible to carry out testing a the prescribed, increased test voltage without enlarging the insulating housing in order to extend the creep distance between the connection terminals of neighbouring phases.Type: GrantFiled: September 12, 2002Date of Patent: July 27, 2004Inventors: Willy Feller, Patrik Kalt, Hans-Jurgen Haars, Hans Weichert, Sandro Liberto

Patent number: 5097104Abstract: A contact arrangement provided for an electrical switching device, particularly for a contactor or protective relay, includes a stationary contact element and a movable contact element. The stationary contact element essentially consists of an elongated current lead-in member, at the end region of which there is affixed a contact member. At this contact member there is adjacently arranged an arc guiding element which is supported at the elongated current lead-in member, but is electrically conductively connected to the current lead-in member solely at an end portion thereof. At the surface or side facing away from the elongated current lead-in member, the arc guiding element is provided on an end surface area confronting the contact member with a projection which is formed of ferromagnetic material and symmetrically arranged in the center of the arc guiding element.Type: GrantFiled: September 11, 1990Date of Patent: March 17, 1992Assignee: Sprecher & Schuh AGInventor: Hans Weichert
