Patent number: 9117613Abstract: A short circuit indicator module is disclosed for an electrical switching device, in particular for a circuit breaker. The electrical switching device is configured to interrupt a current flow in the event of a short circuit and/or an overload in a subordinate power circuit. The module includes a housing, a display facility for indicating tripping of the electrical switching device in the event of a short circuit and a movable unlatching element, it being possible for the display facility to be activated by a movement of the unlatching element and the unlatching element being configured to form a functional connection between the short circuit indicator module and the electrical switching device. The module is configured to test the activatability of the display facility of the short circuit indicator module and/or to test the functional connection between the short circuit indicator module and the electrical switching device.Type: GrantFiled: December 20, 2012Date of Patent: August 25, 2015Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Michael Freimuth, Jürgen Renner

Patent number: 8816802Abstract: An auxiliary tripping device is configured to interrupt a flow of current in the event of an undervoltage and/or a current pulse in a subordinate power circuit. The tripping device includes a spring element, a storage element which can be moved between a tensioned and a detensioned position, a trip element for tripping a trip mechanism of the electrical switching device and an activation element, the storage element being embodied in the tensioned position, when activated by way of the activation element, to emit the stored mechanical energy to the trip element. In an embodiment, a movably supported blocking element is provided, which is connected functionally in a first position to the storage element when the storage element is in the tensioned position, so that the storage element is held by the blocking element and in a second position the blocking element releases the storage element to perform a movement.Type: GrantFiled: December 20, 2012Date of Patent: August 26, 2014Assignee: Siemens AktiengesellschaftInventors: Michael Freimuth, Jürgen Renner

Patent number: 8638183Abstract: A power switch includes switch contacts that are opened via a switch shaft, which, when the switch is triggered, is actuated by way of the trigger slider of a trigger unit, in particular a working current trigger unit. The trigger slider moves the switch shaft by way of the trigger shaft of a switch latch, the trigger unit including electric coil into which an armature extends that is drawn into the coil by electromagnetic forces of attraction when the switch is triggered. A stationary counter armature is disposed in the coil, which counter armature serves as a stop for the armature, so as to increase the forces of attraction. The movement of the armature is transmitted by way of a mechanism to the movement of the trigger slider so as to increase the displacement path of the trigger slider.Type: GrantFiled: June 25, 2010Date of Patent: January 28, 2014Assignee: Siemens AktiengesellschaftInventors: Michael Freimuth, Jürgen Renner, Matthias Weiss

Patent number: 8526153Abstract: In an undervoltage tripping unit of at least one embodiment, an armature acts on a tripping slide via a drum. During tripping, an auxiliary switch is closed. In order to reset the under-voltage tripping unit after tripping, a latching mechanism of an associated circuit breaker acts on the drum via a driver bolt. At the same time, a projecting element is formed on the drum and closes the auxiliary switch when the drum is rotated back. The auxiliary switch therefore need not itself be directly coupled to the latching mechanism.Type: GrantFiled: May 12, 2010Date of Patent: September 3, 2013Assignee: Siemens AktiengesellschaftInventors: Michael Freimuth, Jürgen Renner, Andreas Späth
