The relay is designed for the essential loads. The relay has six independent base parameter controls:
four independent adjustments for essential parameters: the minimum voltage, the maximum voltage, peak phase voltage imbalance value, automatic reset delay for the minimum voltage;
the minimum voltage threshold;the maximum voltage threshold;
the phase/line voltage imbalance value;
the time delay for U=Umin;
trip delay covering all types of the mains voltage faults;
the automatic reset delay.
The relay provides:
RMS phase/line voltage trip;
mode operation switching from the phase voltage monitoring to the line voltage monitoring;
the magnetic starter terminals control possibility;
the separate indication for each type of faults. The mains voltage indication;
self-powered by the three-phase voltage to be monitored (save operation when at least one phase is present (in the three-phase systems with neutral).
