| 20120113557 | ELECTRONIC CIRCUIT BREAKER - A compact electronic circuit breaker is simple to assemble. The circuit breaker has an insulating housing, a switch contact for reversibly contacting a load power circuit to be monitored, a triggering magnet acting by way of a triggering mechanism on the switch contact, and triggering electronics for actuating the triggering magnet. The switch contact, the triggering magnet, and the triggering electronics are fixedly mounted on a printed circuit board and they form a preassembled component together with the printed circuit board. The preassembled component can thereby be inserted in the housing as a unit. | 05-10-2012 |
| 20120007657 | DISCONNECTOR SWITCH FOR GALVANIC DIRECT CURRENT INTERRUPTION - 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. | 01-12-2012 |
| 20110220475 | MINIATURE CIRCUIT BREAKER - 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. | 09-15-2011 |

| 20100187081 | Circuit Breaker Configuration - A circuit breaker configuration contains a number of circuit breakers each to be connected via lines to a system component of a power distribution system and a plurality of control buttons with a respective one of the control buttons connected to a respective one of the circuit breakers. The respective control button for the respective circuit breaker passes through a control panel and is actuated from a front side of the control panel. A coupling element accessible from the front side of the control panel is provided for an interchange of diagnosis data and/or parametrization data. The coupling element is associated with the circuit breakers. | 07-29-2010 |
| 20100123603 | METHOD AND DEVICE FOR MONITORING THE FUNCTION OF A SAFETY UNIT - A method for monitoring a function of a safety unit, in particular of a bilge blower of a boat with a combustion engine, connected via a manually operated switch to a voltage supply. The current flowing through the safety unit is measured and an acoustic alarm is triggered, if a sensor voltage derived from the measured current falls below a reference voltage. | 05-20-2010 |
| 20100061038 | Switching Device - An electrical switching device which enables an electrical system, particularly a power distribution system, is structured rationally and simply. The switching device, in particular embodied in the form of a rail-mounted device, contains a housing and, included therein, a switching unit for interrupting an electrical circuit, and a supply connection for feeding a current to the switching unit. The supply connection has a first coupling contact for connecting to a current busbar, a load connection for connecting a feed conductor of a load circuit to the switching unit, and a return connection which has a connecting terminal for connecting to the return conductor of the load circuit and a second coupling contact connected to the connecting terminal inside the housing for connecting to a second current busbar. | 03-11-2010 |
| 20100007332 | METHOD AND APPARATUS FOR EVALUATING RAPID CHANGES IN CURRENT - 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. | 01-14-2010 |
| 20090160586 | Protection Switch - 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. | 06-25-2009 |
| 20090146766 | Protection Switch - 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. | 06-11-2009 |
| 20090145882 | Protection Switch - A protection switch, particularly for rapid quenching of electrical arcing, 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 a closed position and an open position and a quenching device for quenching electrical arcing of the switch. The quenching device includes a quenching chamber with an inlet and an outlet for the arc. A first running rail connects the fixed contact with a first side wall of the quenching chamber and a second running rail connects a stopping surface, against which the movable contact abuts in the open position of the switching arm, to a second side wall of the quenching chamber. A separation strip extends substantially from side wall to side wall at the outlet of the quenching chamber. | 06-11-2009 |
