This earth leakage relay operates when the leakage current exceeds a predetermined value.
The leakage current is measured through the use of Zero-phase Current Transformer (ZCT) for three-phase system.

<b><u>Block Setting</u></b>

<b>Sensitivity</b>
Specify relay pick-up leakage current.

<b>Multiplier</b>
Specify the multipier factor for leakage current sensitivity setting above.

<b>Time Delay</b>
Specify the relay operating time delay.

<b>Fundamental Frequency (Hz)</b>
Specify the RMS current measurement fundamental frequency, in hertz, of the input signal.

<b><u>Block Input Output</u></b>
<b>I</b>
Three-phase current input to the Earth Leakage Relay

<b>R</b>
Relay output (1-0) control signal, commonly connected to circuit breaker

<b>m</b>
Relay operating time and measured leakage current
