Bei unabhängiger Zeiteinstellung wird die Schraube   9   zweckmässig an einer nicht wirksamen Stelle der Einrichtung eingedreht. Wird jetzt die Schraube l aus dem   Lagerböckchen   entfernt, so kann bei starkem magnetischen Zug, z, B. bei Kurzschluss, die Klinke k unter Überwindung der   rückwärts   angelenkten Feder frei nach oben   ausschwingen,   wodurch der Sperrhebel i freigegeben und die Offnung des () schalters sofort veranlasst wird. Man hat also eine teilweise abhängige Zeiteinstellung. Behält jedoch die Schraube l ihre in der Figur veranschaulichte Stellung, dann ist selbst bei Kurzschluss eine   plötzliche   Auslösung des   ölachalters   unmöglich. 



   PATENT-ANSPRÜCHE :
1.   Auslösevorrichtung   für Oberstromschalter mit Zeiteinstellung, dadurch gekennzeichnet, dass die von der Wirkung des Überstromes unmittelbar bewegten Teile (e) der   Auslösevorrichtung   
 EMI2.1 
 giebig (durch eine   Feder f) verbunden   sind, zum Zwecke, die Zeit für den Ablauf des Hemmwerkes vom Überstrom abhängig oder unabhängig zu machen.

When the time is set independently, the screw 9 is expediently screwed into an ineffective point of the device. If the screw l is now removed from the bearing block, in the event of a strong magnetic pull, e.g. in the event of a short circuit, the pawl k can swing freely upwards, overcoming the backward hinged spring, which releases the locking lever i and the opening of the () switch is initiated immediately. So you have a partially dependent time setting. However, if the screw 1 retains its position illustrated in the figure, a sudden triggering of the oil retarder is impossible even in the event of a short circuit.



   PATENT CLAIMS:
1. Trip device for overcurrent switch with time setting, characterized in that the parts (e) of the trip device which are directly moved by the effect of the overcurrent
 EMI2.1
 are connected generously (by a spring f), for the purpose of making the time for the expiration of the inhibitor dependent or independent of the overcurrent.
