Buena calidad
Funciona perfectamente y lo más importante, no se calienta como le ocurría a los modelos normales

Affidabilità Schneider a un prezzo imbattibile
Ottimo prodotto, rapporto qualità-prezzo davvero eccezionale. Questo interruttore differenziale Schneider Electric Interruttore FI Acti9 iID si presenta solido, ben costruito e molto facile da montare per chi ha un minimo di conoscenza. L’affidabilità del marchio Schneider Electric è una garanzia: l’ho testato personalmente e scatta correttamente, quindi svolge perfettamente il suo lavoro in termini di sicurezza. Per quello che costa, è difficile trovare di meglio. Consigliatissimo!

bon matériel
prix honnête par rapport au prix du magasin local... la série acti9 est plus "pro" que la série resi9 donc à priori je suis tranquille ! précision importante, c'est un interrupteur différentiel, PAS un disjoncteur différentiel.

Discontinued
This item constantly trips the circuit it is in, it has been discontinued should not be for sale. Plus it is very flimsy the way it attaches to the rail
