Patent number: 8098119Abstract: A protection switch includes a plurality of single-pole protection switch modules in a mechanically coherent unit forming a multi-pole protection switch configuration. Each module includes a housing, a switching arm, a moving contact on the switching arm pivotably movable against a fixed contact between closed and open positions, a manual operating mechanism for adjusting the switching arm between the closed and open positions and a tripping mechanism for automatically resetting the switching arm into the open position upon a tripping condition. The manual operating mechanisms of all modules are coupled so that the modules are only switched jointly. The tripping mechanisms of all modules are coupled so that the tripping mechanism of each also trips all others. A one-piece coupling is insertable between adjoining modules for both mechanically fixing the modules to one another and coupling the manual operating mechanisms and the tripping mechanisms of the adjoining protection switch modules.Type: GrantFiled: December 12, 2008Date of Patent: January 17, 2012Assignee: Ellenberger & Poensgen GmbHInventors: Markus Birner, Klaus Loos

Publication number: 20120007657Abstract: A disconnecting apparatus for direct current interruption between a direct current source and an electrical device, in particular between a photovoltaic generator and an inverter, has a current-conducting mechanical switching contact and semiconductor electronics connected in parallel with the switching contact. The semiconductor electronics are non-conducting when the switching contact is closed, wherein a control input of the semiconductor electronics is wired with the switching contact in such a way that, when the switching contact opens, an arc voltage generated as a result of an arc via the switching contact switches the semiconductor electronics to become conducting.Type: ApplicationFiled: September 22, 2011Publication date: January 12, 2012Applicant: ELLENBERGER & POENSGEN GMBHInventors: MICHAEL NAUMANN, THOMAS ZITZELSPERGER, FRANK GERDINAND

Publication number: 20110220475Abstract: A miniature circuit breaker has a housing formed of a housing base of insulating material and a pot-like housing cover, which is or can be positioned onto the housing base. Two elongate and flat contact arms are partially embedded in the housing base parallel with respect to one another in terms of their longitudinal direction. A fixed contact is arranged at an inner end of a first one of the contact arms. A bimetallic snap-action disk with a free end, forming or bearing a moving contact, is fitted at an inner end of the second contact arm at a fastening point. The fastening point, the moving contact and the fixed contact are in this case on an axis which is parallel to the longitudinal direction of the contact arms.Type: ApplicationFiled: March 29, 2011Publication date: September 15, 2011Applicant: ELLENBERGER & POENSGEN GMBHInventor: WOLFGANG ULLERMANN

Patent number: 7978033Abstract: A protection switch, particularly for fast switching, includes at least one single-pole protection switch module having a housing, a movable contact mounted on a switching arm for pivoting against a fixed contact between closed and open positions, a manual operating mechanism manually setting the switching arm between the closed and open positions, and a tripping mechanism automatically resetting the switching arm into the open position upon a tripping condition. The switching arm is spring-loaded in direction of the open position and includes a latch lever latching with the manual operating mechanism, and a contact lever carrying the moveable contact. The latch lever is pivotably mounted on the housing and joined to the contact lever by a hinge. The tripping mechanism includes a trip slider to be displaced by a trip device from a ready position towards a tripping position, to load the switching arm for rotationally fixing the contact lever.Type: GrantFiled: December 12, 2008Date of Patent: July 12, 2011Assignee: Ellenberger & Poensgen GmbHInventors: Klaus Loos, Markus Birner

Patent number: 7834614Abstract: In order to detect and evaluate changes in current as a result of electric arcs, a sensor signal, differentiated on the basis of time, is produced with a sensor-dependent frequency bandwidth whose upper cutoff frequency is 40 MHz and whose lower cutoff frequency is 100 kHz. The sensor signal is taken and an evaluation signal is produced with an upper cutoff frequency of less than or equal to 10 MHz. The evaluation signal is compared with a threshold value and a normalized signal is produced, and a pulse duration of the signal is extended to a prescribed time value.Type: GrantFiled: September 18, 2009Date of Patent: November 16, 2010Assignee: Ellenberger & Poensgen GmbHInventors: Michael Naumann, Markus Miklis

Patent number: 7532095Abstract: An apparatus for remotely actuating a circuit breaker with two stable positions corresponding to a switch-on position and a switch-off position, has a drive mechanism with an electric motor. The apparatus further has first and second switches for switching the motor on and off, a transmission, a coupling mechanism for mechanically coupling the drive mechanism to the circuit breaker and a lever. The transmission can be positioned in two basic positions, and the lever is capable of being moved from a first end position into a second end position with the aid of the drive mechanism. The drive mechanism is configured such that, in the event of the lever being moved over manually from one end position into the other end position, one of the switches is actuated, with the result that the transmission is moved over from one basic position into the other basic position.Type: GrantFiled: May 18, 2007Date of Patent: May 12, 2009Assignee: Ellenberger & Poensgen mbHInventors: Wolfgang Schmidt, Johann Kellermann
