3-phase monitoring relays for phase sequence/Phase break and Over-/Under Voltage for mounting on DIN rails or 11-pin base.
Functional description
The relay is pulled when the phases or the phases + 0 are within the set limits, the relay falls if the limit values are passed after the set time delay (0.1-30s). The relay also monitors phase breaks and phase sequence, at the wrong phase sequence or phase break the relay falls without time delay.
All relevant data, as well as the circuit diagram are clearly marked on the side of the relays.3 LEDs. Green lights up when the control voltage is connected. Yellow lights up when the relay is on and Red flashes during the time, and is lit with a steady light in alarm.
