Si basano su un principio di valutazione elettronica, che garantisce una misurazione più precisa della corrente differenziale. Inoltre, questi dispositivi non risentono della magnetizzazione dell’unità di sgancio.
      Gli interruttori differenziali (RCBO) devono essere testati regolarmente; i tempi di verifica possono essere soggetti a leggi o regolamenti locali. Si raccomanda di eseguire il test ogni 6 mesi in ambienti normali e ogni mese in condizioni gravose. La prova di isolamento deve essere eseguita sui terminali superiori, con il dispositivo in posizione OFF.
