Description

Die Erfindung betrifft eine Kontaktschiebereinheit für eine Schalteinheit aufweisend einen Kontaktschieber mit einem darin geführten beweglichen Kontaktstück, welches von einer Seite von einer Kontaktlastfeder beaufschlagt ist.The invention relates to a contact slide unit for a switching unit comprising a contact slide with a guided therein movable contact piece, which is acted upon by a side of a contact load spring.

Schalteinheiten, insbesondere Leistungsschalter, dienen unter Anderem dem sicheren Abschalten bei einem Kurzschluss und schützen dadurch Verbraucher und Anlagen. Ferner eignen sich elektrische oder mechanische Schalteinheiten für das betriebsmäßige manuelle Schalten von Verbrauchern sowie zur sicheren Trennung einer Anlage vom Stromnetz bei Wartungsarbeiten oder Änderungen an der Anlage. Elektrische Schalteinheiten werden häufig elektromagnetisch betrieben.Switching units, in particular circuit breakers, serve, among other things, the safe switching off in the event of a short circuit and thus protect consumers and systems. Furthermore, electrical or mechanical switching units are suitable for the operational manual switching of consumers as well as for the safe separation of a system from the power network during maintenance work or changes to the system. Electrical switching units are often operated electromagnetically.

Das heißt, derartige Schalteinheiten sind technisch hochwertige elektrische Schaltgeräte mit integriertem Schutz für Motoren, Leitungen, Transformatoren und Generatoren. Ihren Einsatz finden sie an Funktionsstellen mit geringerer Schalthäufigkeit. Derartige Schalteinheiten sind neben dem Kurzschlussschutz auch für den Überlastschutz geeignet.That is, such switching units are high-quality electrical switching devices with integrated protection for motors, lines, transformers and generators. They are used at workstations with a lower switching frequency. Such switching units are suitable in addition to the short circuit protection for overload protection.

Im Fall eines Kurzschlusses schaltet eine elektrische Schalteinheit eine elektrische Anlage sicher ab. Somit bietet diese Sicherungsschutz vor Überlastung. Jeder Leiter, durch den Strom fließt, erwärmt sich mehr oder weniger stark. Die Erwärmung hängt dabei vom Verhältnis der Stromstärke zum Stromleiterquerschnitt ab, der so genannten Stromdichte. Die Stromdichte darf nicht zu groß werden, da sonst durch zu hohe Erwärmung der Leiterisolation ein Verschmoren und möglicherweise ein Brand ausgelöst werden kann.In the case of a short circuit, an electrical switching unit switches off an electrical system safely. Thus, this protection provides protection against overload. Every conductor through which electricity flows heats up more or less. The heating depends on the ratio of the current to the conductor cross-section, the so-called current density. The current density must not be too large, otherwise a too high heating of the conductor insulation can cause a fire and possibly a fire.

Leistungsschalter weisen zwei voneinander getrennt wirkende Auslösemechanismen für den Überlast- und Kurzschlussschutz auf. Beide Auslöser sind in Reihe geschaltet. Den Schutz beim Kurzschluss übernimmt ein zeitlich nahezu unverzögert wirkender elektromagnetischer Auslöser. Bei einem Kurzschluss entklinkt der elektromagnetische Auslöser unverzögert ein Schaltschloss des Leistungsschalters. Ein Schaltanker trennt das Schaltstück, ehe der Kurzschlussstrom seinen Höchstwert erreichen kann.Circuit breakers have two separate release mechanisms for overload and short-circuit protection. Both triggers are connected in series. The protection at Short circuit takes over a timely almost instantaneous acting electromagnetic release. In the event of a short circuit, the electromagnetic release unlocks without delay a circuit breaker of the circuit breaker. A switching armature disconnects the contactor before the short-circuit current can reach its maximum value.

Bei Leistungsschaltern mit einem hohen Schaltvermögen (ICU bis 100 KA bei einem Nennstrom von IN=100A) treten hohe Kurzschlüsse auf, wodurch wiederum große magnetische Kräfte zwischen dem beweglichen Schaltstück und dem Festschaltstück entstehen. Zum Einen sind dies Stromschleifenkräfte zwischen den Feststellstücken und den beweglichen Schaltstücken und zum anderen die weitaus größeren Stromengekräfte zwischen den Silberkontakten. Diese beiden Kräfte bewirken, dass das bewegliche Schaltstück im Kurzschlussfall impulsartig gegen ihre resultierende Federkraft aufgeschleudert wird und gegen die Aufschlagdome im Unterteil prallt.Circuit breakers with high switching capacity (I CU up to 100 KA at a rated current of I N = 100 A) cause high short circuits, which in turn cause large magnetic forces between the moving contact and the fixed contact. On the one hand these are current loop forces between the locking pieces and the movable contact pieces and on the other hand the much larger current forces between the silver contacts. These two forces cause the movable contact piece is impulsively spun against its resulting spring force in the event of a short circuit and rebounds against the impact dome in the lower part.

Außerdem kommt es vor, dass die bereits genannten Stromengekräfte zwischen den Silberkontakten nicht zentral in der Mitte der Kontakte wirken, sondern dezentral weiter am Rand der Kontakte. Zusätzlich zu der öffnenden Kraft in Richtung der Aufschlagdome des Unterteils erfährt das bewegliche Schaltstück daher ein Drehmoment, das zu einer Drehung des beweglichen Schaltstücks um die Längsachse führen kann. Auch das Auftreffen auf die Aufpralldome kann bei ungünstiger Lage des beweglichen Schaltstücks bewirken, dass wiederum ein unerwünschtes Drehmoment eingeleitet wird.It also happens that the above-mentioned current forces between the silver contacts do not act centrally in the middle of the contacts, but decentralized on the edge of the contacts. In addition to the opening force in the direction of the impact dome of the lower part, the movable contact piece therefore experiences a torque which can lead to a rotation of the movable contact piece about the longitudinal axis. The impact on the impact dome can cause unfavorable position of the movable contact piece, in turn, an undesirable torque is initiated.

Unter Extrembelastung kann es vereinzelt vorkommen, dass das bewegliche Schaltstück seine konstruktionsbedingten Freiheitsgrade ausnutzt, und dass es sich durch die eingeleiteten Drehmomente entweder im Kontaktschieber verkeilt oder sich so weit verdreht, dass ein reguläres Kontaktieren zwischen den Kontakten des beweglichen Schaltstücks und des Festschaltstücks nicht mehr möglich ist. In jedem Fall ist eine zuverlässige Funktion des Leistungsschalters nicht mehr gewährleistet.Under extreme load, it may occasionally happen that the moving contact exploits its design-related degrees of freedom, and that it is wedged by the introduced torques either in the contact slide or so far twisted that a regular contact between the contacts of the movable contact piece and the Festschaltstücks no longer possible is. In any case, is a reliable Function of the circuit breaker no longer guaranteed.

Bekannte Kontaktschieber dieser Schalteinheiten weisen häufig zwei Führungssysteme, ein inneres und ein äußeres Führungssystem auf. Das äußere Führungssystem kommt dann zum Einsatz, wenn der Schaltvorgang, das heißt, das Ein- oder Ausschalten, über ein Schaltschloss der Schalteinheit erfolgt. Hierbei entsteht kein Brückendreher.Known contact slides of these switching units often have two guide systems, an inner and an outer guide system. The outer guide system is used when the switching operation, that is, the switching on or off, via a switching mechanism of the switching unit. This does not create a bridge twister.

Das innere Führungssystem kommt im Kurzschlussfall zum Einsatz, wenn der Schaltvorgang über einen Schaltanker, häufig einen Stößel, der Schalteinheit erfolgt. Das heißt, beim Abschalten auf Grund eines Kurzschlusses eilt das bewegliche Schaltstück entlang des inneren Führungssystems dem Kontaktschieber voraus, prallt an Aufschlagflächen im so genannten Unterteil der Schalteinheit ab und fliegt wieder entlang dem inneren Führungssystem zurück. Hierbei fliegt es dem Schaltanker beziehungsweise dem Stößel der Schalteinheit entgegen. Dabei kann es passieren, dass sich das bewegliche Schaltstück und der Stößel außerhalb ihrer Mittellinien treffen, so dass dies zu einem Verdrehen des beweglichen Schaltstückes um seine Längsachse führen kann.The inner guide system is used in the event of a short circuit, when the switching operation via a switching armature, often a plunger, the switching unit takes place. That is, when switching off due to a short circuit, the movable contact piece along the inner guide system leads the contact slide ahead, bounces on impact surfaces in the so-called lower part of the switching unit and flies back along the inner guide system. In this case, it flies against the switching armature or the plunger of the switching unit. It may happen that the movable contact piece and the plunger meet outside their center lines, so that this can lead to a rotation of the movable contact piece about its longitudinal axis.

Wenn das bewegliche Schaltstück im gedrehten Zustand verharrt, treffen bei einem nächsten Einschalten der Schalteinheit nicht mehr die Kontakte, insbesondere Silberkontakte des beweglichen Schaltstücks auf die festen Kontakte der Schalteinheit, so dass es zu Ausfallerscheinungen kommt. Das heißt, ein in einer verdrehten Position verharrendes Schaltstück ist nachteilig, da die Schalteinheit dann nicht mehr einsatzfähig ist. Ein nichtfunktionierendes Schaltstück und eine nichtfunktionierende Schalteinheit sind nachteilig für die elektrischen Verbraucher und die Anlage, in der die Schalteinheit eingebaut ist.When the movable contact piece remains in the rotated state, the contacts, in particular silver contacts of the movable contact piece, no longer strike the fixed contacts of the switching unit when the switching unit is next switched on, which leads to failure phenomena. In other words, a switching piece that remains in a twisted position is disadvantageous because the switching unit is then no longer operational. A non-functioning switching piece and a non-functioning switching unit are detrimental to the electrical loads and the system in which the switching unit is installed.

Die DE 100 61 394 A1 beschreibt eine Kontaktschiebereinheit für eine Schalteinheit mit einem Kontaktschieber mit einem darin geführten beweglichen Kontaktstück, welches von einer Seite von einer Kontaktlastfeder beaufschlagt ist, wobei das bewegliche Kontaktstück in einem Windungsspalt zwischen zwei Windungen der Kontaktlastfeder gelagert ist. Das Dokument SU 955 244 offenbart eine Kontaktschiebereinheit gemäß dem Präambel des Anspruchs 1. Demgemäß besteht die Aufgabe der vorliegenden Erfindung darin, eine Kontaktschiebereinheit für eine Schalteinheit zu schaffen, die derart ausgebildet ist, dass Brückendreher des Schaltstücks vermieden werden, sowie ein Verfahren zur Montage dieser Kontaktschiebereinheit anzugeben.The DE 100 61 394 A1 describes a contact slide unit for a switching unit with a contact slide with a guided therein movable contact piece, which is acted upon by a side of a contact load spring, wherein the movable contact piece is mounted in a winding gap between two turns of the contact load spring. The document SU 955 244 discloses a contact slide unit according to the preamble of claim 1. Accordingly, the object of the present invention is to provide a contact slide unit for a switching unit create, which is designed such that bridge rotors of the contact piece are avoided, and to provide a method for mounting this contact slide unit.

Diese Aufgabe wird erfindungsgemäß durch eine Kontaktschiebereinheit mit den Merkmalen des Patentanspruchs 1 sowie durch ein Verfahren gemäß Patentanspruch 8 gelöst. Vorteilhafte Aus- und Weiterbildungen, welche einzeln oder in Kombination miteinander eingesetzt werden können, sind der Gegenstand der abhängigen Ansprüche.This object is achieved by a contact slide unit with the features of claim 1 and by a method according to claim 8. Advantageous embodiments and developments, which can be used individually or in combination with each other, are the subject of the dependent claims.

Erfindungsgemäß wird diese Aufgabe durch eine Kontaktschiebereinheit gelöst, die einen Kontaktschieber mit einem darin geführten beweglichen Kontaktstück aufweist, welches von einer Seite von einer Kontaktlastfeder beaufschlagt ist. Die Erfindung zeichnet sich inter alia dadurch aus, dass das bewegliche Kontaktstück in einem Windungsspalt zwischen zwei Windungen der Kontaktlastfeder gelagert ist.According to the invention this object is achieved by a contact slide unit having a contact slide with a guided therein movable contact piece, which is acted upon by a side of a contact load spring. The invention is inter alia characterized in that the movable contact piece is mounted in a winding gap between two turns of the contact load spring.

Die Kontaktlastfeder weist vorzugsweise einen vergrößerten Windungsspalt auf, in welchem das bewegliche Kontaktstück gelagert ist. Dadurch entsteht eine formschlüssige Lagerung des beweglichen Kontaktstückes in der Kontaktlastfeder. In Verbindung mit den in den Kontaktschieber integrierten Führungsflächen bewirken die angelegten Windungen der Kontaktlastfeder oberhalb und unterhalb des beweglichen Kontaktstückes einen Schutz gegen Verdrehungen.The contact load spring preferably has an enlarged winding gap, in which the movable contact piece is mounted. This results in a positive mounting of the movable contact piece in the contact load spring. In conjunction with the integrated in the contact slide guide surfaces cause the applied turns of the contact load spring above and below the movable contact piece protection against rotation.

Ein weiterer Vorteil dieses erfindungsgemäßen Konzepts besteht darin, dass man vom ursprünglichen Montagevorgang der Schalteinheit, insbesondere des Leistungsschalters nicht abweichen muss. Lediglich vor dem Zusammenfügen der Brücke mit dem Kontaktschieber muss diese in die Kontaktlastfeder eingelegt werden. Die wesentlichen Änderungen bestehen in einer geringfügigen Änderung am Kontaktschieber, einer Korrektur der gestanzten Brückengeometrie und einer Anpassung der Kontaktlastfedergeometrie.Another advantage of this concept according to the invention is that you do not have to deviate from the original assembly process of the switching unit, in particular the circuit breaker. Only before assembling the bridge with the contact slide must it be inserted into the contact load spring. The main changes consist in a slight change in the contact slide, a correction of the punched bridge geometry and an adjustment of the contact load spring geometry.

Für den Fall, dass die Brücke durch die Stromengekräfte und Stromschleifenkräfte nach unten aufgeschleudert wird, wird sie nun durch ihre formschlüssige Lage in der Kontaktlastfeder sicher in ihrer Position gehalten, auch wenn durch außermittige Krafteinleitung ein Drehmoment auf die Brücke wirkt. Somit ist ein Verkippen oder Verkanten der Brücke im Kontaktschieber nicht mehr möglich.In the event that the bridge is thrown down by the current forces and Stromschleifenkräfte down, it is now held securely in its position by their positive position in the contact load spring, even if a torque acts on the bridge by off-center force application. Thus, a tilting or tilting of the bridge in the contact slide is no longer possible.

In der Erfindung ist es vorgesehen, dass die Windungen der Kontaktlastfeder oberhalb des beweglichen Kontaktstückes durch eine Kontur im Kontaktschieber geführt sind. Die in den Kontaktschieber integrierten Führungen dienen dazu, die Windungen der Kontaktlastfeder, die oberhalb des beweglichen Schaltstücks, also auf der Seite der Kontaktpads angeordnet sind, aufzunehmen. Durch die formschlüssige Lagerung des beweglichen Kontaktstückes in der Kontaktlastfeder und durch die Kontur, die in die Windungen der Kontaktlastfeder oberhalb des beweglichen Kontaktstückes greift, wird eine Verdrehsicherung erzielt.In the invention, it is provided that the turns of the contact load spring are guided above the movable contact piece by a contour in the contact slide. The integrated into the contact slide guides are used to record the turns of the contact load spring, which are arranged above the movable contact piece, ie on the side of the contact pads. Due to the positive mounting of the movable contact piece in the contact load spring and by the contour which engages in the turns of the contact load spring above the movable contact piece, an anti-rotation is achieved.

Eine erfindungsgemäße Weiterführung dieses Konzepts kann darin bestehen, dass die Kontur im Kontaktschieber konisch zulaufend angeordnet ist. Das konische Zulaufen der Kontur gewährleistet so, dass die Windungen oberhalb des beweglichen Kontaktstückes der Kontaktlastfeder sicher aufgenommen und geführt werden.An inventive continuation of this concept may consist in that the contour is arranged conically tapered in the contact slide. The conical tapering of the contour ensures that the windings are securely received and guided above the movable contact piece of the contact load spring.

In einer weiteren speziellen Fortführung des erfindungsgemäßen Konzepts kann es vorgesehen sein, dass die Windungen der Kontaktlastfeder oberhalb des beweglichen Kontaktstücks mit sich verengendem Durchmesser ausgebildet sind. Die mit verengendem Durchmesser zulaufenden Windungen der Kontaktlastfeder oberhalb des beweglichen Kontaktstückes umgeben auf diese Weise mit etwas Spiel die vorzugsweise konisch zulaufende Führung des Kontaktschiebers.In a further special continuation of the inventive concept it can be provided that the turns of the contact load spring are formed above the movable contact piece with narrowing diameter. The tapered diameter tapered turns of the contact load spring above the movable contact piece surrounded in this way with some play the preferably tapered leadership of the contact slide.

In einer besonders bevorzugten Ausgestaltung der Erfindung kann eine technische Weiterführung des erfindungsgemäßen Konzepts darin bestehen, dass zwischen der letzten Windung an der Unterseite des beweglichen Kontaktstücks und der ersten Windung an der Oberseite des beweglichen Kontaktstücks ein Abstandshalter in der Kontaktlastfeder ausgebildet ist. Der Abstandshalter ermöglicht die Ausbildung eines etwas vergrößerten Windungsspalts in der Kontaktlastfeder, so dass das bewegliche Schaltstück auf einfache Art und Weise zwischen der letzen Windung an der Unterseite des beweglichen Kontaktstücks und der ersten Windung an der Oberseite des beweglichen Kontaktstücks positioniert werden kann.In a particularly preferred embodiment of the invention, a technical continuation of the inventive concept may consist in that between the last turn on the underside of the movable contact piece and the first turn on the upper side of the movable contact piece, a spacer is formed in the contact load spring. The spacer allows the formation of a slightly larger winding gap in the contact load spring so that the movable contact can be easily positioned between the last turn on the bottom of the movable contact and the first turn on the top of the movable contact.

In einer weiteren speziellen Fortführung dieses erfindungsgemäßen Konzepts kann es vorgesehen sein, dass der Abstandshalter die Höhe der Längskante des beweglichen Kontaktstückes aufweist. Die Ausbildung des Abstandshalters in der Höhe der Längskante des beweglichen Kontaktstückes ermöglicht ein leichtes Einführen des beweglichen Kontaktstückes in die Kontaktfeder und führt dazu, dass das bewegliche Kontaktstück zwischen der letzten Windung an der Unterseite und der ersten Windung an der Oberseite nahezu spannungsfrei lagert.In a further specific continuation of this inventive concept, it can be provided that the spacer has the height of the longitudinal edge of the movable contact piece. The formation of the spacer in the height of the longitudinal edge of the movable contact piece allows easy insertion of the movable contact piece in the contact spring and causes the movable contact piece between the last turn on the bottom and the first turn at the top stores almost free of stress.

In einer speziellen Ausgestaltung der Erfindung kann ein weiteres Konzept darin bestehen, dass das bewegliche Kontaktstück sich gegenüberliegende Vorsprünge aufweist. Diese Vorsprünge waren bisher halbkonzentrisch ausgeführt und sind in der vorliegenden Erfindung in Form eines viertelkonzentrischen Vorsprungs ausgebildet. In der dadurch gewonnenen Ausnehmung am beweglichen Kontaktstück kann so vorzugsweise der Abstandshalter positioniert sein.In a specific embodiment of the invention, another concept may be that the movable contact piece has opposite projections. These protrusions have heretofore been semi-concentric and are formed in the present invention in the form of a quarter-concentric protrusion. In the recess thus obtained on the movable contact piece, the spacer may thus be positioned in such a way.

Es kann erfindungsgemäß außerdem vorgesehen sein, dass der erfindungsgemäße Kontaktschieber in einem Leistungsschalter Anwendung findet.It can also be inventively provided that the contact slide according to the invention is used in a circuit breaker application.

Die erfindungsgemäße Aufgabe der vorliegenden Erfindung wird außerdem durch ein Verfahren zur Montage einer Kontaktschiebereinheit für eine Schalteinheit gelöst, aufweisend einen Kontaktschieber mit einem darin geführten beweglichen Kontaktstück, welches von einer Seite von einer Kontaktlastfeder beaufschlagt wird inter alia mit den Schritten:

  • Einlegen des beweglichen Kontaktstücks in einen Windungsspalt der Kontaktlastfeder;
  • Zusammenfügen der Baueinheit aus dem derzeitigen beweglichen Kontaktstück mit der Kontaktlastfeder in den Kontaktschieber.
The object of the present invention is also achieved by a method for assembling a contact slide unit solved for a switching unit, comprising a contact slide with a guided therein movable contact piece, which is acted upon by a side of a contact load spring inter alia with the steps:
  • Inserting the movable contact piece into a winding gap of the contact load spring;
  • Assembling the assembly from the current movable contact piece with the contact load spring in the contact slide.

Die erfindungsgemäße Kontaktschiebereinheit für eine Schalteinheit weist einen Kontaktschieber mit einem darin geführten beweglichen Kontaktstück auf. Der Kontaktschieber ist vorzugsweise U-förmig ausgebildet mit einem Mittelbereich, der vier Seitenkanten, eine Oberseite und eine Unterseite aufweist, und zwei gegenüberliegend zueinander angeordneten Seitenführung. Die Seitenführungen münden in den Mittelbereich und weisen an den dazu gegenüberliegenden Endbereichen vorzugsweise kleine Füßchen auf, die als Auflagefläche für das bewegliche Kontaktstück dienen. Im Mittelbereich des Kontaktschiebers ist innenseitig, ausgehend von der Oberseite in Richtung des beweglichen Kontaktstücks eine vorzugsweise konisch zulaufende Kontur angeordnet.The contact slide unit according to the invention for a switching unit has a contact slide with a movable contact piece guided therein. The contact slide is preferably U-shaped with a central region having four side edges, a top and a bottom, and two oppositely disposed side guide. The side guides open into the middle region and have at the opposite end portions preferably small feet, which serve as a support surface for the movable contact piece. In the middle region of the contact slide, a preferably conically tapering contour is arranged on the inside, starting from the top side in the direction of the movable contact piece.

Das bewegliche Kontaktstück weist auf der Oberseite seitlich neben dem Kontaktschieber jeweils ein Kontaktpad auf. Die Unterseite des beweglichen Kontaktstücks lagert auf einer Kontaktlastfeder. Die letzte Windung der Kontaktlastfeder unterhalb des beweglichen Kontaktstücks geht in einen Abstandshalter über, der vorzugsweise die Höhe des beweglichen Kontaktstücks aufweist. Der Abstandshalter geht in die erste Windung der Kontaktlastfeder auf der Oberseite des beweglichen Kontaktstücks über. Dadurch ist das bewegliche Kontaktstück in einem Windungspalt in der Kontaktlastfeder gelagert beziehungsweise geklemmt. Vorzugsweise können die Windungen oberhalb des beweglichen Kontaktstücks mit einem sich verengenden Durchmesser ausgebildet sein. In die Windungen oberhalb des beweglichen Kontaktstücks greift die vorzugsweise konisch ausgebildete Kontur, so dass die Windungen fixiert sind und geführt werden.The movable contact piece has on the upper side laterally next to the contact slide in each case a contact pad. The underside of the movable contact piece rests on a contact load spring. The last turn of the contact load spring below the movable contact piece passes into a spacer, which preferably has the height of the movable contact piece. The spacer merges into the first turn of the contact load spring on top of the movable contact piece. As a result, the movable contact piece is mounted or clamped in a winding gap in the contact load spring. Preferably, the windings above the movable contact piece with a narrowing Diameter be formed. In the turns above the movable contact piece engages the preferably conical contour, so that the windings are fixed and guided.

Die erfindungsgemäße Kontaktschiebereinheit zeichnet sich dadurch aus, dass das bewegliche Kontaktstück eine formschlüssige Lage in der Kontaktlastfeder einnimmt und auch nach Schaltvorgängen sicher in der waagerechten Position gehalten wird. Auch bei einer außermittigen Einleitung der Stromengekräfte und Stromschleifenkräfte, die im Kurzschlussfall auf das bewegliche Kontaktstück wirken und dieses gegen die Aufprallung im Unterteil schleudern, wird das bewegliche Kontaktstück effektiv durch die Kontaktlastfeder geführt. Ein Verkippen oder gar Verkanten des beweglichen Kontaktstücks ist somit nicht mehr möglich und eine sichere Kontaktierung zwischen Festschaltstück und beweglichen Kontaktstück ist auch nach einem Kurzschluss gewährleistet.The contact slide unit according to the invention is characterized in that the movable contact piece occupies a positive position in the contact load spring and is securely held in the horizontal position even after switching operations. Even with an off-center introduction of Stromengekräfte and current loop forces acting on a short circuit on the movable contact piece and this hurl against the impact in the lower part, the movable contact piece is effectively guided by the contact load spring. A tilting or even tilting of the movable contact piece is thus no longer possible and a secure contact between Festschaltstück and movable contact piece is guaranteed even after a short circuit.
