ELR ACTIVATED WHEN MEASURED LEAKAGE CURRENT <0.85

The DIN330 is microprocessors based earth leakage relay with built in self-reclosing function. The earth leakage protection module is designed for measure the low-level current flowing from the live part of the installation to the earth in the absent of the insulation fault. A zero phase current transformer is connected to the relay and function as the sensor for sensing the leakage current. All conductors of the circuit to be protected shall go through the ZCT. While the self reclosing module provide multiple numbers of shots operation. It also incorporates intelligent to differentiate the transient fault or persistent fault.
