Patent number: 9203230Abstract: The invention relates to a line protection switch (1) for protecting an electrical load circuit from an over-current which exceeds a permissible load current. In order to provide a structurally simple, compact and rapidly actuating line protection switch, it is provided with a switching member (6) which can be moved from an operating position into a protection position. Contact elements (2A, 2C) of the line protection switch (1) which can be connected to the load circuit are closed in the operating position and opened in the protection position. The line protection switch (1) according to the invention further has a retention member (10) which produces a magnetic retention field (MH) which is independent of the load current and by means of which the switching member (6) is retained in the operating position, and a counter-force member (14) which is independent of the load current and by means of which the switching member (6) is retained in the protection position.Type: GrantFiled: March 5, 2013Date of Patent: December 1, 2015Assignee: TE Connectivity Germany GmbHInventors: Titus Ziegler, Thomas Haehnel, Matthias Kroeker, Udo Gabel, Peter Sandeck

Patent number: 8946580Abstract: The present invention relates to contactors for unidirectional DC operation with permanent magnetic arc extinguishing. In addition to the blow magnets, the contactors are equipped with compensatory permanent magnets for compensating the magnetic field in the vicinity of the contact bridge in order to prevent contact levitation, i.e., an uncontrolled opening of the contacts that is due to a magnetic force generated by a strong current flowing through the contact bridge. To this end, the compensatory permanent magnets are arranged in the vicinity of the contact bridge and polarized in the opposite direction of the blow magnets. The magnetic field of the compensatory magnets and the current flowing through the contact bridge are generating a magnetic force that acts on the contact bridge and tends to keep the electrical contacts closed.Type: GrantFiled: December 4, 2009Date of Patent: February 3, 2015Assignee: Tyco Electronics AMP GmbHInventors: Ralf Hoffmann, Matthias Kroeker

Patent number: 8467155Abstract: The invention provides a switching device having a contact protection circuit for arcing suppression. The switching device comprises a main relay for interrupting a load path and a dual coil auxiliary having a high resistance coil and a low resistance coil that operate the switching of an auxiliary contact. The auxiliary contact is connected in series with a PTC device and the low resistance coil of the auxiliary relay in a series arrangement. The series arrangement is connected in parallel to the main contact. When the main relay opens, the auxiliary contact is maintained closed during a given time interval due to the magnetic flux generated by the low resistance coil. The given time interval depends on the transition of the PTC device to trip state. In another configuration, the dual coil relay is substituted by two auxiliary relays.Type: GrantFiled: July 13, 2011Date of Patent: June 18, 2013Assignee: Tyco Electronics AMP GmbHInventors: Matthias Kroeker, Joerg Einhorn, Gilles Gozlan
