Situazione di guastoQuando il valore della corrente differenziale, rilevata dal trasformatore toroidale è superiore alla soglia I∆n, il relè RD3 provoca l’apertura dell’interruttore automatico a cui è collegato attraverso una bobina di sgancio.

Collegamento con bobina a lancio di corrente:

La protezione differenziale non è attiva quando questo interruttore è aperto
