Leistungsschalter sind speziell für hohe Ströme ausgelegt. Ein Leitungsschutzschalter ist eine Überstromschutzeinrichtung in der Elektroinstallation und wird insbesondere im Bereich der Niederspannungsnetze eingesetzt. Leistungsschalter und Leitungsschutzschalter garantieren ein sicheres Abschalten bei Kurzschluss und schützen Verbraucher und Anlagen vor Überlast. Sie schützen auch Leitungen vor Beschädigung durch zu starke Erwärmung in Folge eines zu hohen elektrischen Stromes.Protective switching devices, such as circuit breakers or circuit breakers are used in particular as switching and safety elements in electrical energy supply networks. Circuit breakers are specially designed for high currents. A circuit breaker is an overcurrent protection device in the electrical installation and is used in particular in the field of low-voltage networks.

Ein Fehlerstromschutzschalter ist eine Schutzeinrichtung zur Sicherstellung eines Schutzes gegen einen gefährlichen Fehlerstrom in einer elektrischen Anlage. Ein derartiger Fehlerstrom, welcher auch als Differenzstrom bezeichnet wird, tritt auf, wenn ein spannungsführendes Leitungsteil einen elektrischen Kontakt gegen Erde aufweist. Dies ist beispielsweise dann der Fall, wenn eine Person ein spannungsführendes Teil einer elektrischen Anlage berührt: in diesem Fall fließt der Strom als Fehlerstrom durch den Körper der betreffenden Person gegen die Erdung ab. Zum Schutz gegen derartige Körperströme muss der Fehlerstromschutzschalter bei Auftreten eines derartigen Fehlerstroms die elektrische Anlage schnell und sicher allpolig vom Leitungsnetz trennen. Im Allgemeinen Sprachgebrauch werden für einen Fehlerstromschutzschalter auch die Begriffe FI-Schutzschalter (kurz: FI-Schalter) oder RCD (für Residual Current Protective Device) gleichwertig verwendet.A residual current circuit breaker is a protective device to ensure protection against a dangerous fault current in an electrical system. Such a fault current, which is also referred to as differential current, occurs when a live line part has an electrical contact with earth. This is for example the case when a person touches a live part of an electrical system: in this case, the current flows as a fault current through the body of the person concerned against the ground. To protect against such body currents of the residual current circuit breaker must occur when such a fault current, the electrical system quickly and safely disconnect all poles from the mains. In general parlance, the terms residual current circuit breaker (RCD) or RCD (Residual Current Protective Device) are also used equivalently.
Schutzschaltgeräte wie Leistungsschalter, Leitungsschutzschalter oder Fehlerstromschutzschalter sind dazu ausgebildet, den Stromkreis im Falle eines Kurzschlusses, bei Überlast oder bei Auftreten eines Fehlerstromes selbsttätig abzuschalten und somit vom Leitungsnetz zu trennen. Sie weisen hierzu ein Schaltkontaktpaar mit einem feststehenden Schaltkontakt sowie einem relativ dazu bewegbaren Schaltkontakt auf, welches bei Bedarf geöffnet wird, um den Stromfluss zu unterbrechen. Zur elektrischen Kontaktierung mit einem oder mehreren externen Anschlussleitern weisen diese Geräte eine oder entsprechend mehrere Anschlussklemmen auf, in die der Anschlussleiter einsteckbar ist. Durch Betätigen einer entsprechenden Klemmschraube kann der Anschlussleiter sicher geklemmt werden, so dass das Schutzschaltgerät mit dem elektrischen Anschlussleiter sicher verbunden ist.Circuit-breakers such as circuit breakers, miniature circuit breakers or residual current circuit breakers are designed to switch off the circuit automatically in the event of a short circuit, overload or fault current, thus disconnecting it from the mains. For this purpose, they have a switching contact pair with a stationary switching contact and a switching contact which can be moved relative thereto, which is opened when necessary in order to interrupt the flow of current. For electrical contacting with one or more external connection conductors, these devices have one or a plurality of connection terminals into which the connection conductor can be inserted. By pressing a corresponding clamping screw, the connection conductor can be securely clamped, so that the protective switching device is securely connected to the electrical connection conductor.
Bei der elektrischen Ausrüstung von Gebäuden wird zumeist eine Vielzahl von Schutzschaltgeräten benötigt, welche in einem sogenannten Elektroinstallationsverteiler, auch als Verteilerkasten oder kurz als Verteiler bezeichnet, zusammengefasst und nebeneinander angeordnet sind. Bei der Ausrüstung eines solchen Verteilerkastens müssen zum Teil national unterschiedliche Sicherheitsvorschriften beachtet und eingehalten werden. Um die Anforderungen hinsichtlich der einzuhaltenden Luft- und Kriechstrecken zu erfüllen, ist es in manchen Ländern notwendig, die in einem Verteilerkasten nebeneinander angeordneten Schutzschaltgeräte im Bereich ihrer elektrischen Anschlüsse voneinander abzuschotten, d.h. elektrisch voneinander zu isolieren. Dies ist insbesondere bei schmalen Gehäusebauformen der Schutzschaltgeräte der Fall, da hier die elektrischen Anschlüsse der einzelnen Schutzschaltgeräte nahe beieinander liegen. Die Druckschrift
An elektrischen Schutzschaltgeräten werden Leitungen durch Klemmen, in der Regel durch Schraubklemmen, befestigt. Dazu weist das Isolierstoffgehäuse des Schutzschaltgerätes Öffnungen auf, hinter denen sich die Klemmen befinden. Um auch Leiter größeren Querschnitts klemmen zu können, lässt es sich nicht vermeiden, die Klemme und damit die Öffnung des Schutzschaltgerätes so groß zu dimensionieren, dass innenliegende Metallteile mit dem Finger berührt werden können, wodurch die betreffende Person einen elektrischen Schlag erleiden kann. Diese Gefahr ist besonders dann gegeben, wenn Leiter mit einem weit kleineren Querschnitt als dem maximal möglichen Querschnitt an das Schutzschaltgerät angeklemmt sind: in diesem Fall ist ein großer Teil des Klemmenquerschnitts durch ein leitendes Element, beispielsweise eine Klemmschraube oder ein Klemmendruckstück, geschlossen. Diese Klemmschraube oder das Klemmendruckstück liegt dabei unmittelbar hinter der Gehäuseöffnung und kann dabei von einem Installateur oder Anwender mit dem Finger berührt werden, wenn dieser z.B. weitere Geräte in der Verteilung montiert, demontiert oder Anschlussleiter an- oder abklemmt.On electrical protective switching devices, cables are fixed by terminals, usually by screw terminals. For this purpose, the insulating material of the protective device on openings, behind which are the terminals. In order to clamp even conductors larger cross-section, it is unavoidable to dimension the terminal and thus the opening of the circuit breaker so large that internal metal parts can be touched with the finger, causing the person concerned can suffer an electric shock. This danger is particularly present when conductors are clamped with a much smaller cross-section than the maximum possible cross-section of the circuit breaker: in this case, a large part of the terminal cross-section by a conductive element, such as a clamping screw or a clamping pressure piece, closed. This clamping screw or the clamping pressure piece lies directly behind the housing opening and can be touched by a plumber or user with his finger, if this example. other devices are mounted in the distribution, dismantled or connected or disconnected.
Aus der
Es ist deshalb die Aufgabe der vorliegenden Erfindung, eine Isolationsvorrichtung für ein Schutzschaltgerät, insbesondere für einen Leitungsschutzschalter, einen Fehlerstromschutzschalter oder einen Leistungsschalter, zur elektrischen Isolierung des Schutzschaltgerätes im Bereich seiner elektrischen Anschlussklemme, sowie ein Schutzschaltgerät mit einer derartigen Isolationsvorrichtung bereitzustellen, welche
ei-nen sicheren Schutz vor elektrischem Schlag gewährleisten und gleichzeitig eine einfache Bedienbarkeit beim Anschließen eines elektrischen Anschlussleiters ermöglichen.It is therefore the object of the present invention to provide an insulation device for a protective switching device, in particular for a circuit breaker, a residual current circuit breaker or a circuit breaker, for electrical insulation of the protective device in the region of its electrical terminal, and a protective switching device with such an isolation device, which
ei-nen ensure safe protection against electrical shock and at the same time allow easy operation when connecting an electrical connection conductor.
Diese Aufgabe wird durch das elektromechanische Schutzschaltgerät gemäß dem unabhängigen Anspruch gelöst. Vorteilhafte Ausgestaltungen sind Gegenstand der abhängigen Ansprüche.This object is achieved by the electro-mechanical protection device according to the independent claim. Advantageous embodiments are the subject of the dependent claims.
Die erfindungsgemäße Isolationsvorrichtung ist zur Abdeckung eines leitenden Kontaktelements eines elektromechanischen Schutzschaltgerätes, insbesondere eines Leitungsschutzschalters, eines Fehlerstromschutzschalters oder eines Leistungsschalters, vorgesehen, wobei das leitende Kontaktelement hinter einer Gehäuseöffnung des Schutzschaltgerätes angeordnet ist. Die Isolationsvorrichtung weist hierzu einen Grundkörper auf, welcher an einem Gehäuse des Schutzschaltgerätes befestigbar ist und eine Öffnung zum Hindurchführen zumindest einer elektrischen Anschlussleitung aufweist, um diese mit dem Kontaktelement des Schutzschaltgerätes zu kontaktieren. Die Isolationsvorrichtung weist ferner ein Isolationselement auf, welches im Bereich der Öffnung fest aber lösbar mit dem Grundkörper verbunden ist. Die Öffnung weist ihrerseits einen Öffnungsquerschnitt auf, welcher mit Hilfe des Isolationselements an einen Leitungsquerschnitt der elektrischen Anschlussleitung derart anpassbar ist, dass im montierten Zustand der Isolationsvorrichtung am Schutzschaltgerät eine manuelle Berührung des Kontaktelements ausgeschlossen ist.The insulation device according to the invention is provided to cover a conductive contact element of an electro-mechanical protection device, in particular a circuit breaker, a residual current circuit breaker or a circuit breaker, wherein the conductive contact element is arranged behind a housing opening of the protective device. For this purpose, the insulation device has a main body, which can be fastened to a housing of the protective switching device and has an opening for passing at least one electrical connection line in order to contact the latter with the contact element of the protective switching device. The insulation device furthermore has an insulation element which is firmly but detachably connected to the base body in the region of the opening. The opening, in turn, has an opening cross-section which can be adapted to a line cross-section of the electrical connection line with the aid of the insulation element in such a way that manual contact of the contact element is excluded in the installed state of the insulation device on the protection switching device.
Die Isolationsvorrichtung kann, falls nationale Sicherheitsanforderungen - beispielsweise hinsichtlich der einzuhaltenden Luft- und Kriechstrecken - dies erfordern, an einem Schutzschaltgerät im Bereich der elektrischen Anschlussklemme befestigt werden. Dabei wird die Öffnung der Isolationsvorrichtung, durch die die elektrische Anschlussleitung hindurchgeführt werden muss, um mit dem Kontaktelement des Schutzschaltgerätes elektrisch leitend verbunden zu werden, durch das Isolationselement derart verkleinert, dass eine manuelle Berührung des dahinter angeordneten Kontaktelements nicht mehr möglich ist. Der Begriff "Kontaktelement" umfasst dabei alle elektrisch leitenden Bauteile im Anschlussbereich des Schutzschaltgerätes, beispielsweise den Klemmrahmen oder das Druckstück der Anschlussklemme, aber auch den Kontakt selbst. Unter dem Begriff "manuelle Berührung" wird dabei eine Berührung des elektrisch leitenden Kontaktelements durch eine Person mit deren Fingern durch die Öffnung des Isolationselements hindurch verstanden. Ein ungewolltes Berühren eines Kontaktelements, beispielsweise der Anschlussklemme, des Druckstücks oder des Kontakts, wird somit wirksam unterbunden, so dass mit Hilfe der Isolationsvorrichtung ein sicherer Schutz vor elektrischem Schlag realisierbar ist.The insulation device, if national safety requirements - for example, with regard to the creepage distances and creepage distances to be complied with - require this, be attached to a protective switching device in the region of the electrical connection terminal. In this case, the opening of the insulation device, through which the electrical connection line must be passed, in order to be electrically conductively connected to the contact element of the protective switching device, reduced by the isolation element such that a manual contact of the behind arranged contact element is no longer possible. The term "contact element" encompasses all electrically conductive components in the connection region of the protective switching device, for example, the clamping frame or the pressure piece of the terminal, but also the contact itself. Under the term "manual contact" is a touch of the electrically conductive contact element by a person with understood their fingers through the opening of the insulating member. Unintentional contact with a contact element, for example, the terminal, the pressure piece or the contact, is thus effectively prevented, so that with the help of the isolation device, a secure protection against electric shock can be realized.
Die Anpassung des Öffnungsquerschnitts an den Querschnitt der Anschlussleitung mithilfe des Isolationselements wird dadurch erreicht, dass das Isolationselement den Öffnungsquerschnitt teilweise verdeckt. Die Anpassung des Öffnungsquerschnitts kann dabei sowohl durch eine Montage als auch durch eine Demontage des Isolationselements erfolgen: Im Fall einer Montage des Isolationselements am Grundkörper der Isolationsvorrichtung wird der Öffnungsquerschnitt verkleinert, wodurch eine Anpassung an eine Anschlussleitung mit kleinem Leitungsquerschnitt realisierbar ist. Im Falle einer Demontage, d.h. eines Entfernens des Isolationselements vom Grundkörper wird der Öffnungsquerschnitt entsprechend vergrößert, wodurch eine Anpassung an eine Anschlussleitung mit großen Leitungsquerschnitt erreicht wird. Auf diese Weise ist im Bereich der Anschlussklemmen des Schutzschaltgerätes mit Hilfe der Isolationsvorrichtung ein einfacher und kostengünstiger Berührungsschutz der Schutzart IP20 auch für unterschiedliche Leitungsquerschnitte realisierbar. Erfindungsgemäß sind unterschiedlich dimensionierte Isolationselemente mit dem Grundkörper kombinierbar, wodurch der Öffnungsquerschnitt an unterschiedliche Leitungsquerschnitte anpassbar ist. Durch die Verwendung unterschiedlich dimensionierter Isolationselemente, welche unterschiedlich groß sind, aber auf dieselbe Art und Weise am Grundkörper der Isolationsvorrichtung montiert werden, wird eine hohe Flexibilität hinsichtlich der Anpassung der Querschnittsöffnung an unterschiedlich dimensionierte Anschlussleitungen, und damit an unterschiedliche Leitungsquerschnitte, erreicht.The adaptation of the opening cross section to the cross section of the connecting line by means of the insulating element is achieved in that the insulating element partially covers the opening cross section. The adjustment of the opening cross-section can be done both by an assembly and by disassembly of the insulation element: In the case of mounting the insulation element on the main body of the insulation device, the opening cross-section is reduced, whereby an adaptation to a connecting line with a small cross-section can be realized. In the case of dismantling, ie removal of the insulating element from the base body of the opening cross-section is increased accordingly, whereby an adaptation to a connecting cable is achieved with a large cross-section. In this way, in the field of terminals of the protective switching device with the help of the insulation device, a simple and cost-effective protection against contact of the degree of protection IP20 can also be realized for different cable cross-sections. According to the invention differently dimensioned insulation elements can be combined with the base body, whereby the opening cross-section is adaptable to different cable cross sections. By using different sized insulation elements, which are different in size, but are mounted in the same way on the main body of the insulation device, a high flexibility in terms of adaptation of the cross-sectional opening to differently sized connecting lines, and thus to different cable cross-sections, achieved.
In einer weiteren vorteilhaften Weiterbildung der Isolationsvorrichtung ist das Isolationselement durch Einstecken oder Clipsen mit dem Grundkörper verbindbar. Sowohl das Einstecken als auch das Einclipsen des Isolationselements am Grundkörper der Isolationsvorrichtung stellt eine einfache und kostengünstige Montagearte zur Befestigung des Isolationselements am Grundkörper dar.In a further advantageous development of the isolation device, the insulation element can be connected to the base body by inserting or clipping. Both the insertion and the clipping of the insulation element on the base body of the insulation device is a simple and inexpensive way to mount the insulation element to the base body.
In einer weiteren vorteilhaften Weiterbildung der Isolationsvorrichtung ist das Isolationselement einstückig aber lösbar mit dem Grundkörper verbunden. Durch die einstückige Ausführungsform ist eine zeitaufwändige Montage des Isolationselements am Grundkörper entbehrlich, weswegen die Isolationsvorrichtung vergleichsweise kostengünstig herstellbar ist.In a further advantageous embodiment of the isolation device, the insulation element is integrally but detachably connected to the base body. Due to the one-piece embodiment, a time-consuming installation of the insulating element on the main body is unnecessary, which is why the isolation device is relatively inexpensive to produce.
In einer weiteren vorteilhaften Weiterbildung ist die Isolationsvorrichtung auf das Schutzschaltgerät aufsteckbar oder aufschiebbar ausgebildet. Ein Aufstecken oder Aufschieben der Isolationsvorrichtung auf das Schutzschaltgerät ermöglicht eine einfach durchzuführende Montage der Isolationsvorrichtung, insbesondere beim Nachrüsten bestehender Elektroinstallationen. Der Montageaufwand wird dadurch deutlich reduziert.In a further advantageous embodiment, the isolation device is designed plugged or pushed onto the protective switching device. A plugging or pushing the isolation device on the circuit breaker allows easy to perform mounting the insulation device, especially when retrofitting existing electrical installations. The assembly effort is significantly reduced.
In einer weiteren vorteilhaften Weiterbildung der Isolationsvorrichtung ist der Grundkörper im Wesentlichen u-förmig ausgebildet, wobei ein erster Schenkel des u-förmigen Grundkörpers von einer ersten Trennwand und ein zweiter Schenkel des u-förmigen Grundkörpers von einer zweiten Trennwand gebildet sind. Der erste und der zweite Schenkel dienen dazu, das Schutzschaltgerät im Bereich seiner elektrischen Anschlussklemme gegen ein benachbart angeordnetes Schutzschaltgerät, beispielsweise in einem Verteilerkasten, elektrisch zu isolieren. Bei der Anordnung in einem Verteilerkasten können die elektrischen Anschlüsse benachbarter Schutzschaltgeräte nahe beieinander liegen, so dass die vorgeschriebenen Luft- und Kriechstrecken ohne eine zusätzliche Isolierung der Anschlüsse nicht eingehalten werden können. Die erste bzw. die zweite Trennwand, welche zwischen den elektrischen Anschlüssen zueinander benachbart angeordneter Schutzschaltgeräte angeordnet sind, stellt eine derartige Isolierung dar. Über eine Basis des u-förmigen Grundkörpers, welche die beiden Schenkel miteinander verbindet, ist die Isolationsvorrichtung an dem Schutzschaltgerät befestigbar.In a further advantageous embodiment of the isolation device, the main body is substantially U-shaped, wherein a first leg of the U-shaped main body of a first partition and a second leg of the U-shaped base body formed by a second partition are. The first and the second leg serve to electrically isolate the protective switching device in the region of its electrical terminal against a neighboring arranged protective switching device, for example in a distribution box. When arranged in a distribution box, the electrical connections of adjacent protection devices can be close to each other, so that the prescribed clearances and creepage distances can not be met without additional insulation of the connections. The first and the second partition wall, which are arranged between the electrical terminals adjacent to each other arranged protective switching devices, represents such insulation. About a base of the U-shaped body, which connects the two legs together, the insulation device to the protection device can be fastened.
In einer weiteren vorteilhaften Weiterbildung der Isolationsvorrichtung entspricht der äußere Abstand der ersten Trennwand zur zweiten Trennwand im Wesentlichen einer Breite des Schutzschaltgerätes. Damit schließt die Isolationsvorrichtung im Wesentlichen bündig mit den Breitseiten, welche die Breite des Schutzschaltgerätes definieren, ab. Auf diese Weise sind mehrere mit einer Isolationsvorrichtung ausgerüsteter Schutzschaltgeräte ohne zusätzlichen Platzbedarf in einer Reihe nebeneinander anordenbar, beispielsweise in einem Verteilerkasten.In a further advantageous embodiment of the isolation device, the outer distance of the first partition to the second partition substantially corresponds to a width of the protective switching device. Thus, the insulation device is substantially flush with the broad sides, which define the width of the protective device, from. In this way, several equipped with an isolation device protection devices without additional space in a row next to each other can be arranged, for example in a distribution box.
In einer weiteren vorteilhaften Weiterbildung ist die Isolationsvorrichtung durch Kunststoff-Spritzgießen herstellbar. Das Kunststoff-Spritzgießen stellt im Bereich der Massenfertigung ein äußerst kostengünstiges Herstellungsverfahren dar. Vorliegend kann auch das Isolationselement über einen oder mehrere Anguss-Stege an den Grundkörper der Isolationsvorrichtung angespritzt werden. Das Isolationselement deckt dann bereits einen Teil des Öffnungsquerschnitts ab. Zur Anpassung an eine Anschlussleitung mit großem Leitungsquerschnitt wird das Isolationselement durch Trennen der Anguss-Stege herausgetrennt, wodurch der Öffnungsquerschnitt entsprechend vergrößert wird.In a further advantageous development, the isolation device can be produced by plastic injection molding. In the field of mass production, plastic injection molding represents an extremely cost-effective production method. In the present case, it is also possible for the insulating element to be injection-molded onto the main body of the insulation device via one or more sprue webs. The insulation element then already covers part of the opening cross-section. To adapt to a connecting cable with a large cable cross section, the insulating element is separated by separating the sprue webs, whereby the opening cross-section is increased accordingly.
Das erfindungsgemäße elektromechanische Schutzschaltgerät, welches insbesondere als Leitungsschutzschalter, als Fehlerstromschutzschalter oder als Leistungsschalter ausgebildet ist, weist zumindest eine Isolationsvorrichtung der vorstehend beschriebenen Art auf. Hinsichtlich der Vorteile des elektromechanischen Schutzschaltgerätes wird auf die vorstehenden Ausführungen zu den Vorteilen der erfindungsgemäßen Isolationsvorrichtung verwiesen.The electromechanical protective switching device according to the invention, which is designed in particular as a circuit breaker, as a residual current circuit breaker or as a circuit breaker, has at least one insulation device of the type described above. With regard to the advantages of the electromechanical protective switching device, reference is made to the above statements on the advantages of the insulation device according to the invention.
In einer vorteilhaften Weiterbildung ist das Schutzschaltgerät in einem Sammelschienenverbund angeordnet, wobei die Isolationsvorrichtung zur elektrischen Isolierung des Schutzschaltgerätes gegenüber zumindest einem benachbart angeordneten Schutzschaltgerät dient. Gerade bei einer Anordnung im Sammelschienenverbund, bei der eine Vielzahl von Schutzschaltgeräten nebeneinander angeordnet sind, ist eine auf einfache Art und Weise zu realisierende Nachrüstung der einzelnen Schutzschaltgeräte mit den erfindungsgemäßen Isolationsvorrichtungen besonders vorteilhaft.In an advantageous development, the protective switching device is arranged in a busbar network, wherein the insulation device for electrically insulating the protective switching device against at least one adjacent arranged protective switching device is used. Especially with an arrangement in the busbar assembly, in which a plurality of protective switching devices are arranged side by side, a simple way to implement retrofitting the individual protective switching devices with the insulation devices according to the invention is particularly advantageous.

Die Befestigung der Isolationsvorrichtung 100 an einem Schutzschaltgerät 1 kann beispielsweise durch Aufschieben, aber auch durch Aufstecken oder Verrasten erfolgen. Hierzu weist die Isolationsvorrichtung 100 mehrere Befestigungselemente 104 auf, welche im Bereich des Verbindungsbereichs 103 am Grundkörper der Isolationsvorrichtung 100 ausgebildet sind. Zur Versteifung des u-förmigen Grundkörpers weist die Isolationsvorrichtung 100 mehrere Versteifungsrippen 108 auf, welche von der ersten Trennwand 101 bzw. der zweiten Trennwand 102 zum Verbindungsbereich 103 hin verlaufen, um dem Grundkörper der Isolationsvorrichtung 100 eine höhere Steifigkeit zu verleihen.The attachment of the
Ferner weist die Isolationsvorrichtung 100 ein Isolationselement 110 in Form eines Plättchens auf, welches in diesem ersten Ausführungsbeispiel über zwei Anguss-Stege 111 derart mit dem Grundkörper der Isolationsvorrichtung 100 verbunden ist, dass es einen Teil der Öffnung 105 verdeckt. Im dargestellten Zustand ist die Isolationsvorrichtung 100 damit zum Hindurchführen einer elektrischen Anschlussleitung mit kleinem Leitungsquerschnitt vorgesehen. Für den Fall, dass eine elektrische Anschlussleitung mit großem Leitungsquerschnitt durch die Öffnung 105 hindurchgeführt werden soll, um mit dem Kontaktelement des Schutzschaltgerätes 1 elektrisch leitend verbunden zu werden, kann das Isolationselement 110 durch Drehung um eine durch die Anguss-Stege 111 definierte Achse vom Grundkörper getrennt werden, um den Öffnungsquerschnitt der Öffnung 105 entsprechend zu vergrößern. Das Isolationselement 110 ist somit einstückig - und damit fest - aber lösbar mit dem Grundkörper der Isolationsvorrichtung 100 verbunden. Auf diese Weise kann die Isolationsvorrichtung 100 an verschiedene elektrische Anschlussleitungen mit unterschiedlichem Leitungsquerschnitt schnell und einfach angepasst werden.Furthermore, the

Die untere, erste Teilöffnung 105-1 ist dabei zum Hindurchführen einer Sammelschiene oder eines Einspeiseelements vorgesehen, während die obere, zweite Teilöffnung 105-2 zum Hindurchführen der elektrischen Anschlussleitung dient. Der Öffnungsquerschnitt der oberen, zweiten Teilöffnung 105-2 ist dabei wiederum durch das Isolationselement 110 teilweise abgedeckt. Das Isolationselement 110 ist dabei wiederum über zwei Anguss-Stege 111 mit dem Grundkörper verbunden. Zur Anpassung der zweiten Teilöffnung 105-2 an den Leitungsquerschnitt der elektrischen Anschlussleitung kann der Öffnungsquerschnitt der zweiten Teilöffnung 105-2 durch Heraustrennen des Isolationselements 110 vergrößert werden.The lower, first partial opening 105-1 is provided for passing a busbar or a feed element, while the upper, second partial opening 105-2 is used for passing the electrical connection line. The opening cross section of the upper, second partial opening 105-2 is in turn partially covered by the

Ferner sei angemerkt, dass die Isolationsvorrichtung 100 sowie das Isolationselement 110 definitionsgemäß aus einem isolierenden Material - bevorzugt aus einem thermoplastischen oder duroplastischen Kunststoff - gebildet sind. Insbesondere thermoplastische Kunststoffe sind - vor allem bei großen Stückzahlen, wie sie in der industriellen Massenfertigung vorkommenden - mittels des Kunststoff-Spritzguss-Verfahrens äußerst kostengünstig herstellbar, insbesondere, wenn dabei auch der Steg 107 und/oder das Isolationselement 110 an den Grundkörper des Isolationsvorrichtung 100 angeformt werden.It should also be noted that the

Im Bereich der beiden Schmalseiten 6 ist jeweils eine Isolationsvorrichtung 100 am Gehäuse 2 des Schutzschaltgerätes 1 befestigt. In dem dargestellten, montierten Zustand der Isolationsvorrichtung 100 an dem Gehäuse 2 befinden sich die erste Teilöffnung 105-1 sowie die zweite Teilöffnung 105-2 im Bereich der Gehäuseöffnung 8, so dass eine elektrische Anschlussleitung durch die erste Teilöffnung 105-1 oder die zweite Teilöffnung 105-2 hindurch in die Gehäuseöffnung 8 eingesteckt werden kann, um dort mit dem elektrisch leitenden Kontaktelement des Schutzschaltgerätes 1 kontaktiert zu werden. Der Begriff "Kontaktelement" bezeichnet dabei nicht nur den eigentlichen Kontakt des Schutzschaltgerätes 1, sondern umfasst alle im Bereich Gehäuseöffnung 8 angeordneten, elektrisch leitenden Bauteile, also auch den Klemmrahmen und das Druckstück der Anschlussklemme des Schutzschaltgerätes 1.In the region of the two
