Dossena DER3/2D RS485 earth differential relays range DER3 are usable in type TT/TN and LV networks with alternate current. The relays assure a sufficient selection of differential protection because of their wide adjustment of any threshold current dispersion (to 30A) and the threshold for delay intervention (to 10 seconds).
