 Stift 3 zur Berührung gelangt. Da an der   Kurzschlussstelle   die Netzspannung ihren geringsten Wert hat und um so grösser wird, je weiter man sich von der   Kurzschlussstelle   entfernt, so wird die   Ausiösezeit   an der   Kurzachlussstelle   am kleinsten sein. Es wird daher nur derjenige Netzteil abgeschaltet werden, der direkt vom Kurzschluss getroffen wird. 



   Ein gemäss der'Erfindung gebautes Relais ist nicht auf die Verwendung als   Kurzschluss-   relais beschränkt, sondern kann auch für ein Überstromrelais verwendet werden, bei dem die Auslösezeit von irgend einer mechanischen Grösse, z. B. Umlaufszahl eines Motors, dem Druck einer Rohrleitung, der Temperatur in irgend einem'Raume abhängig ist.

   In diesem Falle wird der Gegenkontakt mechanisch von der zu überwachenden Grösse verstellt, oder das Spannungselement wird aus einer Hilfsstromquelle gespeist und die Spannung oder der Widerstand von der zu   überwachenden   mechanischen Grösse abhängig gemacht ; auch steht nichts im Wege, die Auslösezeit von einer anderen elektrischen Grösse abhängig zu machen, während man sie von der Auslösestromstärke belber natürlich nicht abhängig machen wird, da dann das Relais als gewöhnliches stromabhängiges Zeitrelais arbeiten würde.

 Pin 3 comes into contact. Since the mains voltage has its lowest value at the short-circuit point and becomes greater the further one is away from the short-circuit point, the tripping time at the short-circuit point will be the shortest. Only that power supply unit that is directly affected by the short circuit will therefore be switched off.



   A relay built according to the invention is not restricted to use as a short-circuit relay, but can also be used for an overcurrent relay in which the tripping time depends on any mechanical variable, e.g. B. the number of revolutions of a motor, the pressure of a pipeline, the temperature in any space depends.

   In this case, the mating contact is adjusted mechanically by the variable to be monitored, or the voltage element is fed from an auxiliary power source and the voltage or the resistance is made dependent on the mechanical variable to be monitored; Nothing stands in the way of making the tripping time dependent on another electrical quantity, while of course you will not make it dependent on the tripping current strength, since the relay would then work as a normal current-dependent time relay.
