Functional description
The relay monitors that all three phases are live, and that the phase sequence is correct. The relay is on as long as these conditions are met. When monitoring engines, the relay falls when one of the phase-phase voltages is less than 85% of the other phase-phase voltages.
All relevant data, as well as the circuit diagram are clearly marked on the side of the relays
