technical specification. Relay will trip after the release time, if any of the above condition fails.

Output Relay will energize after operatetime if following conditions are satisfied:

1. All phases are present and phase voltages are within the over & under voltage trip levels set on the device.

2. Neutral is present.

3. Phase Sequence is ok.

4. Phase to phase asymmetry is less than value mentioned in

In case of balanced load condition, if neutral is open, virtual neutral is formed at the star point, hence the product will not trip & remain healthy.
