Die Erfindung betrifft einen Niederspannungs-Leistungsschalter mit einer ersten Kontaktanordnung zur Verbindung eines ortsfesten Kontaktes mit einer ersten Stromschiene und mit einer zweiten Kontaktanordnung zur Verbindung eines an einem Kontakthebel angeordneten Gegenkontaktes mit einer zweiten Stromschiene.The invention relates to a low-voltage circuit breaker having a first contact arrangement for connecting a stationary contact with a first busbar and with a second contact arrangement for connecting a counter-contact arranged on a contact lever to a second busbar.

Niederspannungs-Leistungsschalter der genannten Art verfügen über Kontaktanordnungen, um ein schnelles Verbinden beziehungsweise Trennen des Schalters mit stromführenden Schienen zu ermöglichen. Dies ist unter anderem zum Ausbau oder zur Wartung der Niederspannungs-Leistungsschalter wünschenswert. Niederspannungs-Leistungsschalter werden für unterschiedliche Nennströme in unterschiedlichen Größen vorgesehen. Dabei wird angestrebt, die baulichen Abmaße eines Niederspannungs-Leistungsschalters möglichst gering zu halten.Low-voltage circuit breakers of the type mentioned have contact arrangements in order to enable rapid connection or disconnection of the switch with current-carrying rails. This is desirable, inter alia, for removal or maintenance of the low-voltage circuit breakers. Low-voltage circuit breakers are designed for different nominal currents in different sizes. The aim is to keep the structural dimensions of a low-voltage circuit breaker as low as possible.

Niederspannungs-Leistungsschalter der genannten Art können einerseits als Festeinbau-Schalter, andererseits als Einschub-Schalter ausgeführt sein. Bei Einschub-Schaltern wird der Leistungsschalter in einem dafür vorgesehenen Einschubrahmen bewegt und arretiert. Dies ermöglicht ein schnelleres und einfacheres Verbinden beziehungsweise Trennen des Leistungsschalters von den Stromschienen als beim Festeinbau-Schalter. Daher ist es wünschenswert, Festeinbau-Schalter mit einem möglichst geringen Material- und Arbeitsaufwand in Einschub-Schalter umrüsten zu können.Low-voltage circuit breaker of the type mentioned can be performed on the one hand as a fixed switch, on the other hand as a slide-switch. With slide-in switches, the circuit breaker is moved and locked in a slot provided for this purpose. This allows a faster and easier connection or disconnection of the circuit breaker from the busbars as the fixed-mounted switch. Therefore, it is desirable to be able to convert fixed-installation switch with the least possible material and labor in slide-switch.

US 3,343,042 offenbart einen Niederspannungs-Leistungsschalter mit einer ersten Kontaktanordnung zur Verbindung eines ortsfesten Kontaktes mit einer ersten Stromschiene und mit einer zweiten Kontaktanordnung zur Verbindung eines an einen Kontakthebel angeordneten Gegenkontaktes mit einer zweiten Stromschiene, wobei die Stromschienen mindestens einen Kontaktbereich aufweisen, über welchen die Stromschienen zur Ausbildung des Niederspannungs-Leistungsschalters als Einschub-Schalter dauerhaft an einem Einschubrahmen des Niederspannungs-Leistungsschalters anordenbar sind. US 3,343,042 discloses a low-voltage circuit breaker having a first contact arrangement for connecting a fixed contact with a first bus bar and with a second contact arrangement for connecting a contact contact arranged with a counter-contact with a second Busbar, wherein the busbars have at least one contact area over which the busbars for forming the low-voltage circuit breaker as a slide-in switch can be permanently arranged on a slide-in frame of the low-voltage circuit breaker.

Es ist Aufgabe der vorliegenden Erfindung, einen Niederspannungs-Leistungsschalter der vorgenannten Art anzugeben, welcher mit minimalem Material- und Arbeitsaufwand von einem Festeinbau-Schalter in einen Einschubschalter umrüstbar ist.It is an object of the present invention to provide a low-voltage circuit breaker of the aforementioned type, which can be converted with minimal material and labor from a fixed switch in a slide-in switch.

Diese Aufgabe wird erfindungsgemäß gelöst durch die Merkmale im kennzeichnenden Teil des Anspruchs 1 im Zusammenwirken mit den Merkmalen im Oberbegriff des Anspruchs 1.This object is achieved by the features in the characterizing part of claim 1 in conjunction with the features in the preamble of claim 1.

Besonders vorteilhaft an der vorliegenden Erfindung ist, dass die bereits vorhandenen Stromschienen eines Festeinbau-Schalters für die Umrüstung in einen Einschub-Schalter auf einfachste Art und Weise wieder verwendet werden können. Dazu weisen die Stromschienen mindestens einen Aufnahmebereich für Haltemittel auf, über welchen die Stromschienen zur Ausbildung des Niederspannungs-Leistungsschalters als Festeinbau-Schalter dauerhaft an der Außenseite des Niederspannungs-Leistungsschalters anordenbar sind.A particular advantage of the present invention is that the already existing busbars of a fixed switch for retrofitting into a slide-in switch in the simplest way can be used again. For this purpose, the busbars on at least one receiving area for holding means, via which the busbars for forming the low-voltage circuit breaker as a permanent installation switch permanently on the outside of the low-voltage circuit breaker can be arranged.

Durch den vorgesehenen Kontaktbereich können die Stromschienen direkt am Einschubrahmen angeordnet werden. Dabei sollen die Flächen des Kontaktbereiches mit der zu kontaktierenden Fläche des Einschubrahmens plan abschließen. Dadurch, dass die Stromschienen einen Aufnahmebereich für Haltemittel aufweisen, sind sie dauerhaft mit einem Haltemittel beaufschlagbar und können hierdurch dauerhaft am Einschubrahmen eines Leistungsschalters arretiert werden.By the aforementioned design of the busbars, it is possible to use these in a fixed installation switch to arrange directly on the fixed switch, but it is also possible to permanently arrange these busbars at a conversion of the fixed switch in a slide-in switch after removal from the fixed switch to the slide-in frame of a slide-switch, so that the conversion of a fixed installation Switch in a slide-in switch with minimal material costs associated with, since this conversion only an additional drawer frame is necessary. Due to the intended contact area, the busbars can be arranged directly on the slide-in frame. In this case, the surfaces of the contact area with the surface to be contacted of the insertion frame plan to complete. The fact that the busbars have a receiving area for holding means, they are permanently acted upon by a holding means and can thereby be locked permanently on the insertion frame of a circuit breaker.

In einer besonders bevorzugten Ausführungsform weisen sowohl die erste als auch die zweite Stromschiene identische Abmaße auf. Hierdurch wird vorteilhafterweise erreicht, dass sowohl für die erste Stromschiene als auch für die zweite Stromschiene die gleichen Kontaktanordnungen, welche vorzugsweise als Trennkontakt-Anordnungen ausgeführt sind, verwendet werden können.In a particularly preferred embodiment, both the first and the second busbar identical dimensions. In this way, it is advantageously achieved that the same contact arrangements, which are preferably designed as isolating contact arrangements, can be used both for the first busbar and for the second busbar.

Nach einer weiteren bevorzugten Ausführungsvariante sind die Stromschienen bei der Ausbildung des Niederspannungs-Leistungsschalters als Einschub-Schalter derart an dem Einschubrahmen anordenbar, dass sie die gleiche Einbautiefe wie die Stromschienen bei der Ausbildung des Niederspannungs-Leistungsschalters als Festeinbau-Schalter aufweisen. Hierdurch wird gewährleistet, dass die Stromschienen lediglich über Haltemittel an ihren dafür vorgesehenen Bereichen an dem Einschub-Schalter dauerhaft angeordnet werden müssen, um eine Umrüstung vom Festeinbau-Schalter in einen Einschub-Schalter zu realisieren. Dadurch, dass die an einem Einschubrahmen angeordneten Stromschienen die gleiche Einbautiefe wie die Stromschienen beim Festeinbau-Schalter aufweisen, sind keine weiteren Anpassungs- oder Umbauarbeiten notwendig.According to a further preferred embodiment, the busbars in the formation of the low-voltage circuit breaker as a slide-in switch can be arranged on the slide-in frame that they have the same depth as the busbars in the formation of the low-voltage circuit breaker as a fixed switch. This ensures that the busbars must be permanently arranged only on holding means at their designated areas on the slide-in switch to realize a conversion from the fixed switch into a slide-in switch. The fact that arranged on a drawer busbars the same depth as the Busbars have the fixed switch, no further adjustment or conversion work is necessary.
