Abstract
E' descritto un interruttore automatico comprendente un primo elemento di collegamento (17) per la commutazione dei contatti fissi (10, 10), installato in un percorso di corrente principale. Il primo elemento di collegamento è azionato da un meccanismo di commutazione del circuito utilizzante un elettromagnete a voltaggio (60), un meccanismo di separazione forzata dei contatti in condizioni di cortocircuito utilizzante un elettromagnete a corrente collegato in serie al percorso principale, e un meccanismo di sgancio a molla sensibile al flusso di sovracorrente per operare. Il meccanismo di separazione forzata dei contatti in condizioni di cortocircuito comprende un meccanismo di collegamento comprendente una funzione di auto-tenuta/auto-ripristino tra il primo elemento di collegamento e l'elettromagnete a corrente.
