75 Patent-An Sprüche:75 patent claims: 1. Hitzdraht für thermisch wirkende Überstromrelais, dadurch gekennzeichnet, daß ein die Schaltkontakte steuernder Hitzdraht mit einer von ihm getragenen, isolierten Heizwicklung in Reihe geschaltet ist.1. Hot wire for thermally acting overcurrent relays, characterized in that that a hot wire controlling the switching contacts is connected in series with an insulated heating coil carried by it is. 2. Hitzdraht nach Anspruch 1, dadurch gekennzeichnet, daß der Hitzdraht und die Heizwicklung so bemessen sind, daß bei kleineren Überlastungen das Ansprechen des Relais infolge indirekter Beheizung des Hitzdrahtes durch die Heizwicklung, bei großen Überlastungen dagegen durch direkte Erwärmung des Hitzdrahtes go infolge seines Ohmschen Widerstandes erfolgt.2. Hot wire according to claim 1, characterized in that the hot wire and the heating coils are dimensioned in such a way that they respond in the event of minor overloads of the relay as a result of indirect heating of the hot wire by the heating coil, but in the case of large overloads takes place by direct heating of the hot wire go as a result of its ohmic resistance.
