Die Erfindung bezieht sich auf eine Einrichtung zum Fernabschalten von Verbrauchern in Netzen, die durch Fehlerstromschutzschalter geschützt sind, insbesondere in Notsituationen. The invention relates to a device for remote shutdown of consumers in networks that are protected by residual current circuit breakers, especially in emergency situations.

Es sind sogenannte Einrichtungen zur Not-Aus-Schaltung auf dem Markt, bei denen von einem handbetätigbaren Schalter bzw. Taster über Steuerleitungen auf ein Relais eingewirkt wird, das einen Hauptschalter im Netz zum Auslösen bringt Solche Einrichtungen müssen am zu schützenden Verbraucherplatz, beispielsweise am Laborplatz, von Anfang an installiert sein, oder die Einrichtung ist nachträglich unter erhöhtem Aufwand zu installieren. There are so-called emergency stop devices on the market, in those of a manually operated switch or button via control lines a relay is acted upon, which triggers a main switch in the network Such facilities must be at the consumer place to be protected, for example on Laboratory space, to be installed from the start, or to be set up afterwards to install with increased effort.

Der Erfindung liegt die Aufgabe zugrunde, eine Einrichtung zum Fernabschalten von durch Fehlerstromschalter geschützten Verbrauchern in Notsituationen zu entwickeln, die ohne zusätzlich zu verlegende Steuerleitungen auskommt und in üblichen Steckdosen, sogenannten Schuko-Steckdosen, wie ein Verbraucher eingesteckt werden kann. The invention is based on the object of a device for remote shutdown to develop consumers protected by residual current switches in emergency situations, which works without additional control lines and in common sockets, so-called Schuko sockets, how a consumer can be plugged in.

Die geschilderte Aufgabe wird mit einer Einrichtung gelöst, die die Merkmale nach dem kennzeichnenden Teil des Hauptanspruchs aufweist. Diese Einrichtung erzeugt an einer Stelle zwischen Fehlerstromschutzschalter und Verbraucher eine Asymmetrie, die den Fehlerstromschutzschalter zum Ansprechen bringt Dadurch erübrigt sich ein eigener Hauptschalter zum Unterbrechen des Netzes. Diese Einrichtung kommt also mit extrem wenigen zusätzlichen Bauteilen aus. Sie kann an einer im Blickfeld liegenden Stelle in eine Steckdose eingesetzt werden. Sie läßt sich jederzeit wieder abziehen und an anderer Stelle verwenden. Die Begrenzungswiderstände sind lediglich so zu wählen, daß im Streubereich der Netzspannung mindestens der Nennauslösestrom des vorgeschalteten Fehlerstromschutzschalters fließen kann. The object is achieved with a device that the Has features according to the characterizing part of the main claim. This facility generates a at a point between the residual current circuit breaker and the consumer Asymmetry that causes the residual current circuit breaker to respond. This makes it unnecessary has its own main switch to interrupt the network. This facility is coming so with extremely few additional components. You can look at one at one be inserted into a socket in a lying position. She leaves again at any time peel off and use elsewhere. The limiting resistors are only to be selected in such a way that at least the rated tripping current is within the range of the mains voltage of the upstream residual current circuit breaker can flow.

Es ist günstig, durch eine Anzeigelampe die Bereitschaft der Einrichtung anzuzeigen. Wenn zwischen den Verbindungsleitungen zu den Steckanschlassen ein Lampentransformator mit der Anzeigelampe eingeschaltet ist, erhält man auch eine Kontrolle, ob das Betätigen der Einrichtung zum Abschalten des Verbrauchers geführt hat, indem die Lampe erlischt Zweckmãßigerweise wird die Anzeigelampe im Betätigungsorgan angeordnet. It is convenient to indicate the readiness of the facility by means of an indicator light to display. If there is a lamp transformer between the connecting lines to the plug-in connections when the indicator lamp is switched on, you can also check whether it has been actuated the device has led to the disconnection of the consumer in that the lamp goes out The indicator lamp is expediently arranged in the actuator.

The invention is to be reproduced schematically with the aid of one in the drawing Exemplary embodiment are explained in more detail: In FIG. list the basic structure illustrates in FIG. FIG. 2 is an embodiment of the external structure of FIG Facility reproduced.

Die Einrichtung zum Fernabschalten von Verbrauchern in Notsituationen weist ein Gehäuse 1 mit zwei Steckanschlüssen 2 und Schutzleiterkontakten 3 auf. Die Steckanschlüsse 2 sind über Begrenzungswiderstände 4 und jeweils einen mittels eines Betätigungsorgans 5 einschaltbaren Kontakt 6 mit dem Schutzleiterkontakt 3 verbunden. Die Begrenzungswiderstände 4 sind so bemessen, daß im Streubereich der Netzspannung mindestens der Nennauslösestrom des vorgeschalteten Fehlerstromschutzschalters fließen kann. The device for remote switching off of consumers in emergency situations has a housing 1 with two plug connections 2 and protective conductor contacts 3. The plug connections 2 are via limiting resistors 4 and each one by means of an actuating member 5 switchable contact 6 with the protective conductor contact 3 tied together. The limiting resistors 4 are dimensioned so that in the spread of the Mains voltage at least the rated tripping current of the upstream residual current circuit breaker can flow.
