RNPP-311M line voltage monitoring relay is designed for protection of three phase loads against major types of mains faults, such as: RMS voltage reaching beyond admissible thresholds – over and under voltage Phase loss or Single phasing Phase sequence order violation or reverse phase sequence Phase coincidence or shorting of two or more phases Phase Imbalance or asymmetry The device performs monitoring of the main circuit parameters and de-energizes (trip) load when the parameters fall beyond specified boundaries. Presence of true RMS voltage in the mains Load status (On/Off) Type of fault Adjustment potentiometers allow for setting: Tripping threshold for the minimum/the maximum voltage, (% of the rated voltage) Time delay for load re-energizing (reset) after the circuit parameters recovery Tripping time delay for load de-energizing (trip) in case of all circuit voltage faults With DIP switches on the device’s front panel the user can select

Three Phase Line Voltage Monitoring, Under voltage, Over voltage, Phase loss (single phasing), Phase Imbalance, Reverse phase sequence
