ELRDIN310 Earth Leakage Relay
ELRDIN-310 is a earth fault and digital microprocessor based relay. This relay comprehensively detect and activate trip protection to medium and low voltage applications. It is accurate, reliable and more resistant to vibration and shock than traditional electromechanical relays, and current measurement based on fundamental frequency,can prevents nuisance tripping
