Abstract

Dispositif de protection pour moteur électrique, comprenant un stator doté d'un bobinage de marche (11) et d'un bobinage de démarrage (12); une source d'alimentation (F) fournissant du courant auxdits bobinages de marche (11) et de démarrage (12); et des interrupteurs d'alimentation (60) reliant le bobinage de marche (11) et le bobinage de démarrage (12) à la source d'alimentation (F) lorsqu'ils sont en position de fermeture. Le dispositif de l'invention comprend au moins un thermocontact (70) reliant de manière fonctionnelle et électriquement la source de courant (F) aux interrupteurs d'alimentation (60) auxquels il est relié thermiquement afin d'en détecter la température et de couper le courant qui les alimente ces interrupteurs (60) lorsque l'un quelconque d'entre eux atteint une valeur déterminée prédéfinie et supérieure à une valeur prédéterminée de température de marche maximum des interrupteurs (60).
