Earth Leakage Relay (Digital)

DELAB Earth Leakage Relay is a microprocessor-based electronic protection device designed to recognize low-level leakage or unbalanced current due to insulation loss on conductors or faulty equipment installed in the network. It incorporates a real time continuous display of the earth leakage current value in true RMS ampere and allows the isolation of the faulty network or equipment. A ring-type zero current transformer is used to detect and provide the continuous measurement of the leakage current. Standard: IEC: 61000-4-2/4-4/4-5/255-5:1
