Patent number: 9064658Abstract: A switching apparatus for an electrical switching device is disclosed, in particular an electrical circuit breaker, for safeguarding at least two poles. A tripping element is included for each pole, supported moveably between a rest position and a tripping position. A common switching frame, movable between a pre-tension position and a switching position, is actively connected for force transmission to frame sections of the at least two tripping elements for the movement of the switching frame into the switching position upon movement of the tripping element into the tripping position. At least one spring element is embodied to apply force to the frame sections of the at least two tripping elements in the direction of the rest position of the at least two tripping elements.Type: GrantFiled: December 5, 2012Date of Patent: June 23, 2015Assignee: SIEMENS AKTIENGESELLSCHAFTInventor: Torsten Ahlert

Patent number: 8947182Abstract: A selective release with a moving element is disclosed. The moving element is here mounted such that the moving element, in addition to the motion about its swivel axis, is guided in its motion by way of a brace. As a result of this, the moving element is mounted such that the trajectory of the blocking element essentially runs in a plane which extends transversely to the direction of flow of the flow channel.Type: GrantFiled: June 8, 2012Date of Patent: February 3, 2015Assignee: Siemens AktiengesellschaftInventors: Torsten Ahlert, Marc Liebetruth

Patent number: 8748764Abstract: A casing of a circuit breaker for nominal currents above 250 A that enables at least one rigid busbar to be swung in to make contact with at least one switching pole attached in the casing. The casing may include a bottom section that cuboidally includes a rectangular base area and two rectangular side faces connected to the base area and running parallel to one another. Adjacent side faces are connected to one another via at least two stays which are arranged away from the opposing openings, delimited by the side faces, of the cuboidal bottom section, so that a switching pole can be inserted between the stays into the bottom section and so that a rigid busbar can be swung in at one of the two openings in order to make contact with the switching pole, when busbar and bottom section are each premounted, for example in a switching cabinet.Type: GrantFiled: December 14, 2011Date of Patent: June 10, 2014Assignee: Siemens AktiengesellschaftInventors: Torsten Ahlert, Jan Grunwald, Katja Manthey

Patent number: 8735752Abstract: A multipole electrical switching device is disclosed with an outer housing in which at least two separate switching pole housings are accommodated. In at least one embodiment, the at least two separate switching pole housings on walls facing towards one another, each have a least one mounting which form a mounting pair assigned to one another. In at least one embodiment, for mechanical connection of the at least two separate switching pole housings, the mounting pair is assigned at least one connection device which engages into the two mountings forming the mounting pair. The two mountings forming the mounting pair, in relation to a dividing joint formed between the two facing walls, each form an undercut, whereby the at least one connecting device engages behind the undercuts and the at least one connecting device is formed in a primary process in one piece on the outer housing.Type: GrantFiled: September 26, 2011Date of Patent: May 27, 2014Assignee: Siemens AktiengesellschaftInventors: Torsten Ahlert, Joerg-Uwe Dahl, Ludvik Godesa, Marc Liebetruth, Milos Petracek

Patent number: 8553385Abstract: A release for an electrical switching arrangement includes at least two switching contacts, which are arranged in a housing and are isolated if the current flowing via the switching contacts has exceeded a predetermined threshold value. The release includes an actuating element, which responds, counter to the force of a restraining apparatus, to a pressure which is generated by an arc occurring in an isolating zone of the switching contacts. The isolating zone is surrounded by the housing, and actuates a shutdown mechanism which brings about automatic interruption of the current path. The actuating element has a movable element, which forms a blocking element in a flow channel, which is connected to the isolating zone. The blocking element performs a predetermined control movement at the pressure which is intended to result in shutdown.Type: GrantFiled: March 26, 2010Date of Patent: October 8, 2013Assignee: Siemens AktiengesellschaftInventor: Torsten Ahlert

Patent number: 8378243Abstract: An arrangement including at least two separate switch pole housings and a joining facility for joining the switch pole housings. Each of the switch pole housings forms an insulating enclosure of a switching space for receiving a single switch pole of an electric switching device. A side wall of a first switch pole housing, facing a second one of the switch pole housings, includes at least one recess for receiving at least one joining device of the joining facility. The at least one recess forms a first undercut with respect to a side wall and a first locating surface in parallel with a front wall of the housing. The at least one joining device engages behind the first undercut and is braced against a first locating surface.Type: GrantFiled: September 28, 2010Date of Patent: February 19, 2013Assignee: Siemens AktiengesellschaftInventors: Torsten Ahlert, Jörg-Uwe Dahl, Ludvik Godesa, Marc Liebetruth

Patent number: 7038155Abstract: A latching mechanism is for locking an actuating shaft of an electrical switch, which can be transferred from an OFF position into an ON position by a drive train counter to the force of at least one first spring, in its ON position. The latching mechanism includes a first lever, which is pivotably coupled to the drive train of the actuating shaft and is supported against a stop held in a locking position. For accelerated release of the actuating shaft, also provided is a second lever, which has a working surface assigned to the stop. In this case, the second lever is held in a first stop position against the first lever by way of a second spring. When the second lever pivots under the action of an initiating force, which opposes the force of the second spring, the working surface acts in such a way on the stop that the stop is transferred into a release position.Type: GrantFiled: April 30, 2004Date of Patent: May 2, 2006Assignee: Siemens AktiengesellschaftInventors: Torsten Ahlert, Joerg-Uwe Dahl, Marc Liebetruth
