Description

Die vorliegende Erfindung betrifft ein Installationsgerät gemäß dem Oberbegriff des Anspruchs 1 (GB-A-783470).The present invention relates to an installation device according to the preamble of claim 1 (GB-A-783470).

Installationsgeräte dieser Gattung zur Montage an Hutschienen sind im allgemeinen Sicherungsautomaten bzw. Leitungsschutzschalter (nachfolgend kurz als LS-Schalter bezeichnet) mit standardisierten Montageabschnitten entsprechend der Form der Hutschiene und genormten elektrischen Anschlüssen zur Verwendung für sogenannte Sammelschienen, jedoch mit unterschiedlichen Auslösecharakteristiken und Nennstromstärken.Installation devices of this type for mounting on top hat rails are generally circuit breakers or circuit breakers (hereinafter referred to as LS switch) with standardized assembly sections according to the shape of the DIN rail and standardized electrical connections for use for so-called busbars, but with different ones Tripping characteristics and nominal currents.

Aus dem Stand der Technik ist ein Installationsgerät dieser Gattung bekannt, welches aus einem im wesentlichen rechteckigen, flach bauenden Gehäuse besteht, an dessen schmaler Vorderseite eine manuell betätigbare Schaltereinrichtung vorgesehen ist. Die schmale Rückseite ist als Montageabschnitt zur Befestigung des Gehäuses an einer Hutschiene ausgebildet. Das Gehäuse ist in der Regel aus Isolationsgründen aus einem Kunststoffmaterial gefertigt, welches zu zwei Gehäusehälften gegossen ist, die unter Ausbildung eines Gehäusehohlraums zusammengefügt und beispielsweise mittels Nieten miteinander verbunden sind. Die Innenseiten der Gehäusehälften sind dabei entsprechend der einzelnen Schalterbauteile oder Komponenten vorgeformt, die in dem Gehäusehohlraum teils ortsfest, teils beweglich untergebracht sind. Präziser ausgedrückt sind an den Innenseiten der zwei Gehäusehälften zum einen rippen- oder leistenförmige Vorsprünge angeordnet, welche beim Zusammenfügen der Gehäusehälften den Gehäusehohlraum in mehrere unterschiedlich dimensionierte Hohlraumbereiche zur Aufnahme der Schalterkomponenten zergliedern. Zum anderen sind eine Anzahl von Befestigungssockeln vorgesehen, in denen jeweils ein Sackloch ausgebildet ist. In diesen Sacklöchern sind zur drehbaren Lagerung von Schalterkomponenten wie Kupplungsteilen, Kontakten usw. benötigte Achsen einzeln verpreßt oder eingeklebt. Hierbei dienen einfache Stahlstifte als Achsen, auf denen die entsprechenden, drehbaren Schalterkomponenten gleitgelagert sind.An installation device is this from the prior art Known genus, which consists of a substantially rectangular, flat housing is made on its narrow front a manually operated switch device is provided is. The narrow back is as a mounting section for attachment the housing is formed on a top-hat rail. The housing is usually made of a plastic material for insulation reasons manufactured, which is cast into two housing halves which is joined together to form a housing cavity and connected to each other for example by means of rivets are. The inside of the housing halves are corresponding the individual switch components or components preformed, those in the housing cavity partly stationary, partly movable are accommodated. Are expressed more precisely on the inside of the two housing halves on the one hand rib or strip-shaped Projections arranged, which when assembling the housing halves the housing cavity into several different Dimensioned cavity areas to accommodate the switch components dissect. Second, there are a number of mounting bases provided, in each of which a blind hole is formed is. In these blind holes are for rotatable storage of switch components such as coupling parts, contacts etc. Axles individually pressed or glued. Serve here simple steel pins as axes on which the corresponding rotatable switch components are mounted on sliding bearings.

Es hat sich nunmehr gezeigt, daß sich bei dieser Variante der Befestigung der Achsen das Problem einer geringen mechanischen und/oder thermischen Belastbarkeit und Festigkeit der Achslagerungen ergibt. LS-Schalter bzw. deren Komponenten erhitzen sich teilweise im Betrieb, wobei die Wärme über die Metallstifte in das Gehäuse abgeleitet wird. Kunststoff hat nicht nur die Eigenschaft eines ausgezeichneten elektrischen Isolators sondern auch eines schlechten Wärmeleiters. D.h. Wärme innerhalb des Gehäuses wird nur mangelhaft nach außen abgegeben, wodurch sich insbesondere im Bereich der Achsbefestigungen solche Temperaturspitzen im Gehäuse ergeben können, die ein Erweichen des Kunststoffmaterials bewirken. In diesem Zustand können die Achsen ihre Relativlage zueinander verändern, wodurch die Funktionsfähigkeit des LS-Schalters beispielsweise aufgrund verringerter Beweglichkeit der drehbaren Schalterkomponenten oder deren Dejustierung beeinträchtigt werden kann. Unterstützt wird diese Relativlageveränderung durch äußere Kräfte auf die Achsen insbesondere bei federvorgespannten Schalterkomponenten. Über die drehbaren mechanischen Schalterkomponenten, welche an den Achsen gelagert sind, wird nämlich auf die Achsen eine Kraft in Folge beispielsweise einer Federvorspannung ausgeübt, die über das entsprechende Sackloch in das Schaltergehäuse eingeleitet wird. Kommt es in dem Installationsgerät nun zu einer Erwärmung, weicht der Kunststoff des Gehäuses auf, so daß die Achsen in Richtung der Kraft verschoben oder verschwenkt werden. Dabei ist zu bemerken, daß LS-Schalter dieser Gattung zahlreiche Achsengruppen aufweist, deren Schalterkomponenten gegeneinander vorgespannt sind, d.h. die entgegengesetzt ausgerichtete Kräfte aufnehmen müssen.It has now been shown that the Fastening the axes the problem of low mechanical and / or thermal resilience and strength of the axle bearings results. Circuit breakers or their components heat up partly in operation, with the heat in via the metal pins the housing is derived. Plastic not only has the property an excellent electrical insulator also a bad heat conductor. That Heat within the Housing is poorly released to the outside, resulting in Such temperature peaks, particularly in the area of the axle mountings in the housing can result in a softening of the Effect plastic material. In this state, the axes change their relative position to each other, reducing the functionality of the circuit breaker, for example, due to reduced Mobility of the rotatable switch components or their Misalignment can be affected. Is supported this change in relative position due to external forces on the axes especially with spring-loaded switch components. about the rotatable mechanical switch components, which on the Axes are stored, namely a force in on the axes Follow, for example, a spring preload, which over the corresponding blind hole is introduced into the switch housing becomes. If the installation device now heats up, softens the plastic of the housing so that the axes be moved or pivoted in the direction of the force. there it should be noted that circuit breakers of this type have numerous axis groups has, the switch components against each other are biased, i.e. the opposing forces have to record.

Eine weitere technische Variante für die Lagerung der drehbaren Schalterkomponenten sieht die Anordnung von sogenannten Platinenschlössern vor, bei denen in eine Metallplatte eine Mehrzahl von Durchgangslöchern ausgebohrt sind, in denen die Lagerungsachsen in Form von Stahlstiften stecken.Another technical variant for the storage of the rotatable Switch components see the arrangement of so-called circuit board locks before, in which in a metal plate a plurality are drilled out from through holes in which the bearing axes stuck in the form of steel pins.

Beide Varianten haben jedoch den gemeinsamen Nachteil, daß sie relativ teuer und aufwendig sind. Bei der erst genannten Variante muß jeder Stift einzeln in die im Gehäuse ausgebildeten Sacklöcher eingesetzt und verklebt werden. Bei der zweit genannten Variante erhöhen sich die Materialkosten infolge der Anordnung der Metallplatte, was sich insbesondere bei einer Massenproduktion erheblich bemerkbar macht.However, both variants have the common disadvantage that they are relatively expensive and complex. In the first variant each pin must be individually in the trained in the housing Blind holes are inserted and glued. With the second named The material costs increase as a result of the variant Arrangement of the metal plate, which is particularly the case with a Mass production makes it noticeably noticeable.

Angesichts dieser Problematik besteht die Aufgabe der Erfindung darin, ein Installationsgerät dieser Gattung zu schaffen, dessen Funktionsfähigkeit auch unter thermischer und/oder mechanischer Belastung seiner Schalterkomponenten verbessert wird, ohne daß sich dessen Herstellungskosten gegenüber einem herkömmlichen Schalter erhöhen.In view of this problem, there is the object of the invention in creating an installation device of this type, the Functionality even under thermal and / or mechanical Load on its switch components is improved without that its manufacturing costs compared to a conventional Increase the switch.

Diese Aufgabe wird erfindungsgemäß durch ein Installationsgerät mit den im Patentanspruch 1 angegebenen Merkmalen gelöst.This object is achieved by an installation device solved with the features specified in claim 1.

Gemäß diesem Patentanspruch 1 hat das Installationsgerät ein Kunststoffgehäuse, in dem eine Anzahl von Gerätekomponenten untergebracht ist, die beweglich auf im Gehäuse befestigten Achsen lagern. Erfindungsgemäß sind zumindest zwei Achsen durch einen Steg miteinander verbunden. Dieser Steg ist dabei als ein zum Gehäuse externes Bauteil ausgebildet. Der Vorteil dieser Ausgestaltung besteht darin, daß Kräfte, welche auf die zwei Achsen in im wesentlichen entgegengesetzte Richtungen einwirken, von dem Steg als Druck- oder Zugkräfte aufgenommen werden, wodurch das Gehäuse selbst unbelastet bleibt. Andere Kräfte, deren Richtung nicht der Ausrichtung des Stegs folgen werden durch den Steg auf verbundenen Achsen verteilt, d.h. deren Einleitung in das Gehäuse erfolgt über die zumindest zwei Achsen und den dazwischen angeordneten Steg, wodurch die Belastung pro Flächeneinheit erheblich verringert bzw. die Kraftangriffsfläche auf das Gehäuse erhöht werden kann. Eine Veränderung der ursprünglichen Relativposition der Achsen aufgrund thermischer und mechanischer Belastung wird somit wirkungsvoll verhindert.According to this claim 1, the installation device Plastic housing that houses a number of device components which is movable on axles fixed in the housing to store. According to the invention, at least two axes are through connected a bridge. This web is as one external component designed for the housing. The advantage of this Design consists in that forces acting on the two Axes act in essentially opposite directions, are absorbed by the web as compressive or tensile forces, whereby the housing itself remains unloaded. Other forces, whose direction will not follow the orientation of the web distributed through the web on connected axes, i.e. their introduction into the housing via the at least two axes and the bridge arranged in between, whereby the load per Area unit significantly reduced or the force application area can be increased to the housing. A change in original relative position of the axes due to thermal and mechanical stress is effectively prevented.

Auch das Gehäuse wird geringeren thermischen Belastungsspitzen ausgesetzt, da die Wärmeenergie aufgrund des Stegs und die damit vergrößerte Gesamtfläche der Achsen-Stegbaugruppe besser verteilt und abgeleitet werden kann.The housing will also experience lower thermal stress peaks exposed because of the thermal energy due to the web and with it enlarged total area of the axis web assembly better can be distributed and derived.

Darüber hinaus wird durch die erfindungsgemäße Stegform ein nur geringer Mehraufwand an Material betrieben, der mehr als nur kompensiert werden kann, dadurch, daß beim Zusammenbau des Geräts die zwei miteinander verbundenen Achsen in einem einzigen Schritt gleichzeitig montiert werden. Dies erleichtert den Montagevorgang der Achsen und verkürzt insgesamt die Montagezeit.In addition, the web shape according to the invention is a only little extra work on material that does more than just can be compensated by the fact that when assembling the device the two interconnected axes in one Step assembled at the same time. This simplifies the assembly process of the axles and reduces the assembly time overall.

Gemäß dem Anspruch 2 ist es ferner vorgesehen, daß die zwei Achsen und der Steg einen U-förmigen Bügel bilden, wobei nach Anspruch 3 der U-förmige Bügel ein entsprechend gebogener Metallstift ist. Dies hat den Vorteil, daß die Achsen auf besonders kostengünstige Weise, nämlich durch Biegen oder Stanzen aus einem preiswerten Material, beispielsweise einem Metalldraht einstückig hergestellt werden können.According to claim 2, it is further provided that the two Axes and the web form a U-shaped bracket, whereby after Claim 3 of the U-shaped bracket a correspondingly bent metal pin is. This has the advantage that the axes are special inexpensive way, namely by bending or punching made of an inexpensive material, for example a metal wire can be made in one piece.

In diesem Fall erfolgt der Einbau des U-förmigen Bügels gemäß der Weiterbildung nach Anspruch 4 derart, daß die durch den Steg miteinander verbundene Achsen unter Zug- oder Druckspannung gegeneinander stehende Komponenten lagern, wobei sich die Achsen über den Steg derart gegeneinander abstützen, daß eine verringerte Krafteinleitung in das Gehäuse erfolgt. In anderen Worten ausgedrückt, verläuft der Steg entlang der teilweise zu erwartenden gegensätzlichen Kraftrichtungen, die auf die verbundenen Achsen einwirken.In this case, the U-shaped bracket is installed in accordance with of further training according to claim 4 such that the Bridge connected axes under tension or compression store opposing components, whereby the Support axes against each other over the web so that a reduced force is introduced into the housing. In other Expressed in words, the web runs along the partially anticipating opposite directions of force on the associated Act axes.

Auch die Ausbildung des Gehäuses vereinfacht sich, da wie bisher im Stand der Technik nicht eine Anzahl von Sackbohrungen entsprechend der Anzahl von Achsen sondern eine verringerte Anzahl von Nuten vorgesehen werden müssen, in die der Steg des U-förmigen Bügels eingesetzt und darin verpreßt oder verklebt wird.The design of the housing is also simplified, as before not a number of blind holes in the prior art according to the number of axes but a reduced number of grooves must be provided in which the web of the U-shaped Used bracket and pressed or glued therein becomes.

Weitere vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Further advantageous embodiments of the invention are the subject of subclaims.

Die Erfindung wird nachstehend anhand eines bevorzugten Ausführungsbeispiels unter Bezugnahme auf die begleitenden Zeichnungen näher erläutert.The invention is described below using a preferred exemplary embodiment with reference to the accompanying drawings explained in more detail.

Gleichzeitig übt die Feder 20 je nach Lage des Knebels 16 auf das Eingriffsbauteil 19 eine Kraft in Rotationsrichtung um dessen Lagerung am Knebel 16 aus. On one axis 11 of the housing edge in the middle section of the housing arranged bracket 7 is an operating lever member 16 (short toggle) rotatably mounted, consisting of a lever 17 protruding from the housing and a thick-walled one Cylinder 18, which is the hub for storage on the Axis 11 forms. There is an eccentric in the cylinder wall an engagement member 19 rotatably supported, which a spring 20 in the direction of rotation of the cylinder (according to FIG. 2 biased to the left). The spring 20 is on her free end hooked to a pin 21 which is integral with the Housing half 1 is formed. At the same time, the spring 20 exercises depending on the position of the toggle 16 on the engagement member 19 a Force in the direction of rotation around its bearing on the gag 16.

Das freie Ende des Eingriffsbauteils 19 (gemäß Fig. 2 rechtes Ende) bildet einen Zapfen, der senkrecht zur Bildebene gemäß Fig. 2 nach hinten vorsteht und in einer Kerbe 22 eines Kontaktfingers 23 einrastbar ist. Dieser Kontaktfinger 23 lagert wiederum auf einer inneren Achse 14 des anderen, gemäß Fig. 2 rechtsseitigen Bügels 8 und ist mittels einer Feder 25 in eine Richtung vorgespannt, in welcher der Kontaktfinger 23 außer Eingriff mit einem ortsfesten Leiterkontakt 24 ist. Die gezeigte Feder 25 ist dabei an ihrem freien Ende an der anderen, gehäuserandseitigen Achse 13 des gleichen Bügels 10 eingehakt.The free end of the engagement member 19 (right in FIG. 2 End) forms a spigot that is perpendicular to the image plane Fig. 2 protrudes to the rear and in a notch 22 of a contact finger 23 can be snapped into place. This contact finger 23 is stored again on an inner axis 14 of the other, according to FIG. 2 right side bracket 8 and is by means of a spring 25 in a Biased direction in which the contact finger 23 except Engagement with a fixed conductor contact 24 is. The one shown Spring 25 is at its free end on the other side of the housing Axis 13 of the same bracket 10 hooked.

Ferner ist ein Auslösehebel 26 in Form einer Wippe auf der inneren Achse 12 des im Mittenabschnitt angeordneten Bügels 9 gelagert, dessen einer Hebelschenkel mit dem Zapfen des Eingriffsbauteils 19 in Eingriff bringbar ist, um diesen aus der Kerbe 22 des Kontaktfingers 23 zu drücken und dessen anderer Hebelschenkel mit einem Bimetallelement (nicht gezeigt) für ein Verschwenken des Auslösehebels 26 in Eingriff bringbar ist.There is also a release lever 26 in the form of a rocker on the inner one Axis 12 of the bracket 9 arranged in the middle section is supported, one of which has a lever arm with the pin of the engagement component 19 is engageable to this from the To press notch 22 of the contact finger 23 and its other Lever arm with a bimetallic element (not shown) for one Swiveling the trigger lever 26 can be brought into engagement.

Die exakte Funktionsweise des vorstehend nur abschnittsweise beschriebenen LS-Schalters ist aus dem Stand der Technik hinlänglich bekannt, so daß auf entsprechende Veröffentlichungen verwiesen werden kann. Lediglich zum Verständnis der Erfindung wird eine allgemeine Erläuterung des Bewegungsablaufs der drehbaren Schalterkomponenten sowie des Kräfteverlaufs zwischen den beschriebenen Achsen nachfolgend gegeben:The exact functioning of the above only in sections described circuit breaker is sufficient from the prior art known, so that appropriate publications can be referred. For understanding the invention only is a general explanation of the movement of the rotatable Switch components and the course of forces between the described axes given below:

In Fig. 2 wird der ausführungsgemäße LS-Schalter in einer Schaltstellung gezeigt, in welcher ein Leitungskontakt geschlossen ist.In Fig. 2, the circuit breaker according to the embodiment is in a Switch position shown, in which a line contact closed is.

In dieser Stellung befindet sich der Knebel 16 in einer gemäß Fig. 2 nach links umgelegten Position, in der das Eingriffsbauteil 19 an bezüglich der Drehachse 11 des Knebels 16 nach rechts verschwenkt ist und somit die auf das Eingriffsbauteil 19 einwirkende Feder 20 gespannt ist. Der Zapfen des Eingriffsbauteils 19 ist dabei in die Kerbe 22 des Kontaktfingers 23 eingerastet und drückt diesen somit gegen den ortsfesten Leiterkontakt 24, wobei die gezeigte Spiralfeder 25 zur Vorspannung des Kontaktfingers 23 gespannt ist. Ferner ist in dieser Schaltstellung der Auslösehebel 26 nicht mit dem Eingriffselement 19 in Berührung.In this position, the toggle 16 is in accordance with Fig. 2 to the left folded position in which the engagement member 19 with respect to the axis of rotation 11 of the toggle 16 is pivoted to the right and thus onto the engagement component 19 acting spring 20 is tensioned. The pin of the engagement component 19 is in the notch 22 of the contact finger 23 snapped into place and presses it against the fixed conductor contact 24, the coil spring 25 shown for prestressing of the contact finger 23 is excited. Furthermore, in this Switch position of the release lever 26 not with the engagement element 19 in touch.

Das nicht gezeigte Bimetallelement ist elektrisch über ein Kabel (ebenfalls nicht gezeigt) mit dem Kontaktfinger 23 verbunden, so daß in der Schaltstellung gemäß der Fig. 2 ein elektrischer Strom über das Bimetallelement, das Kabel und den Kontaktfinger 23 auf den ortsfesten Leiterkontakt 24 übertragen wird. Bei einer Überlastung erhitzt sich das Bimetallelement und verbiegt sich derart, daß es mit dem Auslösehebel 26 in Eingriff kommt, um diesen zu verschwenken. Hierdurch kommt der Auslösehebel 26 mit dem Eingriffsbauteil 19 in Berührung und drückt dessen Zapfen aus der Kerbe 22 des Kontaktfingers 23. In diesem Augenblick wird der Kontaktfinger 23 durch die Federvorspannung verschwenkt, wodurch der Kontakt zwischen dem Kontaktfinger 23 und dem ortsfesten Leiterkontakt 24 unterbrochen wird.The bimetallic element, not shown, is electrical via a cable (also not shown) connected to the contact finger 23, so that in the switch position according to FIG. 2 an electrical Current over the bimetal element, the cable and the contact finger 23 transferred to the fixed conductor contact 24 becomes. In the event of an overload, the bimetal element heats up and bends so that it with the release lever 26 in Intervention comes to pivot this. Through this comes the Release lever 26 with the engaging member 19 in contact and presses its pin from the notch 22 of the contact finger 23. In At this moment, the contact finger 23 by the spring bias pivots, causing contact between the contact fingers 23 and the fixed conductor contact 24 interrupted becomes.

Um ein schnelles Auslösen des LS-Schalters zu gewährleisten ist es erforderlich, den Kontaktfinger 23 mit einer relativ großen Federkraft vorzuspannen. Die Anordnung des gemäß Fig. 2 rechtsseitigen Bügels 8 ist dabei derart gewählt, daß ein Teil der Federkräfte, die auf die gehäuserandseitige Achse 13 des Bügels 8 einwirken, über den Steg 10 auf die andere, innere Achse 14 übertragen werden, auf welche die Rückziehkräfte der Spiralfeder 25 über den Kontaktfinger 23 einwirken. Da Komponenten dieser Kräfte entgegengesetzt zueinander ausgerichtet sind, eliminieren sich diese und werden somit nicht mehr in das Kunststoffgehäuse 1 eingeleitet. Andere, nicht sich gegenseitig eliminierende Kraftkomponenten werden zumindest auf beide Achsen 13, 14 verteilt und über diese Achsen 13, 14 sowie den Steg 10 in das Gehäuse 1 eingeleitet. Auf diese Weise erhöht sich die Kraftangriffsfläche im Gehäuse 1 gegenüber beispielsweise einem einzelnen Stift, wie dies aus dem Stand der Technik bekannt ist.To ensure that the circuit breaker is triggered quickly it required the contact finger 23 with a relatively large Preload spring force. The arrangement of the right-hand side according to FIG. 2 Strap 8 is chosen such that part of the Spring forces on the housing-side axis 13 of the bracket 8 act on the other inner axis 14 via the web 10 are transferred to which the retraction forces of the coil spring 25 act on the contact finger 23. Because components these forces are aligned opposite to each other, eliminate them and are therefore no longer in the Plastic housing 1 initiated. Others, not each other eliminating force components are at least on both axes 13, 14 distributed and over these axes 13, 14 and the web 10 introduced into the housing 1. This way it increases the force application surface in the housing 1 compared to, for example a single pin, as is known in the art is.

Ferner wird der U-förmige Bügel 8 insbesondere als Achse für jene Bauteile eingesetzt, welche thermischen Belastungen ausgesetzt sind und die somit Wärme über die Achsen in das Gehäuse einleiten. Aufgrund der erhöhten Kraftangriffsfläche erhöht sich natürlich auch der Flächenanteil, über den Wärme in das Gehäuse 1 abgegeben werden kann. Durch eine erhöhte Wärmeabgabe steigert sich folglich der Kühlungseffekt und verringern sich lokale Temperaturspitzen, welche eine Erweichung des Kunststoffmaterials des Gehäuses 1 bewirken können. Insofern bleibt dem Gehäuse 1 auch im Betrieb die Fähigkeit erhalten, Kräfte ohne plastische Deformationen aufzunehmen. Der Bügel 7 ist thermisch und kräftemäßig weniger belastet. Sein Einbau erfolgt lediglich zur Reduktion der Montagekosten. Die besonders hohe thermische Belastung des Bügels 8 ergibt sich daraus, daß der darauf angeordnete Kontaktfinger 23 metallisch über eine Litze mit dem Bimetallelement verbunden ist und somit direkt die Wärme des Bimetallelementes zugeführt bekommt.Furthermore, the U-shaped bracket 8 is used in particular as an axis for used components that are exposed to thermal loads are and thus heat through the axes in the housing initiate. Increased due to the increased force application area of course, the proportion of area over which heat enters the Housing 1 can be delivered. Through an increased heat emission consequently, the cooling effect increases and decreases local temperature peaks, which soften the plastic material of the housing 1 can cause. In this respect remains the housing 1 also have the ability to withstand forces without absorbing plastic deformations. The bracket 7 is less stressed thermally and in terms of strength. It is installed only to reduce assembly costs. The particularly high one thermal stress on the bracket 8 results from the fact that the contact fingers 23 arranged thereon are metallic via a stranded wire is connected to the bimetal element and thus directly the heat of the bimetallic element.

Des weiteren wird durch die Verwendung des Bügels 8 der gesamte an dem Bügel 8 angebrachte Kontaktmechanismus vormontierbar. Auch hierdurch können die Montagekosten weiter gesenkt werden.Furthermore, by using the bracket 8, the entire on the bracket 8 attached contact mechanism pre-assembled. The installation costs can also be reduced further in this way.
