   In Fig. 5 ist die. Verwendung der Erfindung an Hitzdrahtstrombegrenzern dargestellt. 



    Der Hitzdraht, der   die Unterbrechung des Stromes in bekannter Weise bewirken soll, besteht aus zwei oder auch mehreren Teilen, die je durch den Strom von einer der Verbindungen beeinflusst werden, und zwar wird in dem gezeichneten Beispiel der Teil 13 von dem durch die Verbindung   I   und der Teil 14 von dem durch die Verbindung 2 fliessenden Strom betätigt. Wird einer der Teile 13, 14 aus dünnerem Draht gemacht als der andere, so wird der Einfluss des Stromes auf die beiden Teile ein verschiedener sein, indem die Ausdehnung des   ffitzdrahtes   der Gesamtausdehnung der verschiedenen Teile bzw. dem Mittel der Ausdehnungen der Hitzdrahtteile entsprechen wird.

 EMI2.1
 



   In Fig. 5 is the. Use of the invention shown on hot wire current limiters.



    The hot wire, which is supposed to cause the current to be interrupted in a known manner, consists of two or more parts, each of which is influenced by the current from one of the connections, namely in the example shown the part 13 of that through connection I. and the part 14 actuated by the current flowing through the connection 2. If one of the parts 13, 14 is made of thinner wire than the other, the influence of the current on the two parts will be different, in that the extension of the wire will correspond to the total extension of the various parts or the mean of the extension of the hot wire parts.
 EMI2.2
 
1.

   Circuit arrangement for current limiters, characterized in that two or more coils are arranged around the same core of the electromagnet controlled by the interruptions, each of which is influenced by a consumption line, so that the maximum load can be set at several consumption points with different tariffs with a single current limiter can.
