Abstract
L'invention concerne un circuit de protection pour moteur à courant continu comportant un contact de commande branché en série avec le moteur et s'ouvrant sous l'effet d'un courant excessif. Le circuit est caractérisé en ce qu'il est prévu également un composant à valeur de seuil qui produit un signal de sortie quand la tension établie par résistance-série dépasse une valeur limite prédéterminée et en ce qu'il est prévu un organe de temporisation à l'aide duquel le contact de commande peut être amené de façon retardée dans sa position d'ouverture en fonction du signal de sortie du composant à valeur de seuil. Application à des moteurs d'équipements d'automobiles.
