 <Desc/Clms Page number 2> 

 



   Der Schalter ist in beiden Ansichten jeweils in ausgeschalteter Stellung gezeichnet. In dieser Stellung ist die Fehlerstromauslösemechanik ebenfalls nicht funktionsbereit. Wird der Schalter eingeschaltet, bewegt sich der Schaltknebel-6-nach rechts (Fig. 3). Gleichzeitig wird der Bolzen --24-- im Langloch des   Zwischenhebels --23-- nach   links geführt, so dass der Auslösehebel   --18-- unter   Einwirkung der   Schenkelfeder --21-- sich   mit seinem   Anschlag --19-- an   der   Nase-20-des Klinkenhebels-12b-abstützt.

   Eine zweite Ausführungsmöglichkeit des   erfindungsgemässen   Schutzschalters ist in Fig. 4 dargestellt. Alle zur Erläuterung nicht erforderlichen Darstellungen wurden weggelassen und sind entsprechend aus Fig. 3 zu übernehmen. Die Funktion des Fehlerstromauslösemechanismuses ist analog der an Hand Fig. 3 beschriebenen. Lediglich der Walzenkörper --13-- wurde durch einen beweglichen Kontakt --30-- ersetzt. Wird die Mechanik durch Fehlerstrom ausgelöst, so entklinkt der   Mitnehmerhebel-17-den   beweglichen   Kontakt --30-- und   dieser schliesst den Stromkreis einer

   Durch den Führungsschlitz im   Zwischenhebel --23-- kann   der Schalter sowohl von Hand mit dem   Knebel-6-,   als auch durch überstrom und Kurzschluss ausgelöst werden, ohne dass die Auslösemechanik des Fehlerstromauslösers geschaltet wird. Durch besondere Ausbildung der Welle   - -16--   (eventuell Freilauf) wird nur die Auslösebewegung vom   Auslösehebel --18-- auf   das Schaltwerk --5-- übertragen, nicht aber vom Schaltwerk auf den Auslösehebel. 



   Die in Fig. 3 dargestellte   Schutzschalter-Ausführung   kann leicht mit einer Wiedereinschaltsperre versehen werden. Dabei müsste der   Zwischenhebel --23-- nicht   direkt mit dem Schaltknebel-6-gekuppelt werden, sondern mit einem ebenfalls auf der   Achse --8-- sitzenden   zweiten Schaltknebel. Eine Auslösung, durch den Fehlerstromauslöser hervorgerufen, würde bewirken, dass der Schaltknebel - 6-durch das   Schaltwerk --5-- in   die Ausschaltstellung gebracht wird. Der zweite Knebel bleibt hingegen in der Einschaltstellung stehen und hält dadurch über den   Zwischenhebel --23-- und   den

   The switch is drawn in both views in the off position. In this position, the residual current release mechanism is also not operational. When the switch is turned on, the toggle-6-moves to the right (Fig. 3). At the same time, the bolt --24-- is guided to the left in the elongated hole of the intermediate lever --23-- so that the release lever --18-- comes into contact with its stop --19-- under the action of the torsion spring --21-- the nose-20-of the ratchet lever-12b-is supported. As soon as a fault current is detected in the summation current transformer, an electrical voltage occurs on the secondary winding,

Roller body-13-free, -24-the intermediate lever-23-and the release lever rotatably connected to this - likewise back into the position shown.

   When switching on again after a fault current trip, the switch knob - 6 - (Fig. 3: the switch knob position shown corresponds to the switch-off position) is turned to the right and takes the roller body-13-

 is guided to the left in the elongated hole of the intermediate lever --23-- so that the stop -19 of the release lever --18-- latches with the nose --20-- of the ratchet lever --12b--. The residual current release mechanism is operational again.



   A second possible embodiment of the circuit breaker according to the invention is shown in FIG. All representations not required for explanation have been omitted and are to be taken over from FIG. 3 accordingly. The function of the fault current release mechanism is analogous to that described with reference to FIG. Only the roller body --13-- was replaced by a movable contact --30--. If the mechanism is triggered by a fault current, the driver lever -17-unlatches the moving contact --30-- and this closes the circuit of a

 the same way as the roller body-13- returned to the latching position shown.



   Through the guide slot in the intermediate lever --23--, the switch can be triggered manually with the toggle -6, as well as through overcurrent and short-circuit, without the trigger mechanism of the residual current release being switched. Due to the special design of the shaft - -16-- (possibly freewheel), only the release movement is transmitted from the release lever --18-- to the switchgear --5--, but not from the switchgear to the release lever.



   The circuit breaker design shown in FIG. 3 can easily be provided with a restart lockout. The intermediate lever --23-- would not have to be coupled directly to the shift toggle -6-, but with a second shifting toggle, which is also located on the axis --8--. A trip caused by the residual current release would cause the switch knob - 6 - to be brought into the off position by the switching mechanism --5--. The second toggle, on the other hand, remains in the on position and thus holds it via the intermediate lever --23-- and the
