## Description

RNPP-311M 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 â over and under voltagePhase loss or Single phasingPhase sequence order violation or reverse phase sequencePhase coincidence or shorting of two or more phasesPhase Imbalance or asymmetryThe device performs monitoring of the main circuit parameters and de-energizes (trip) load when the parameters fall beyond specified boundaries.The front panel LEDs display the following:Presence of true RMS voltage in the mainsLoad status (On/Off)Type of faultAdjustment 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 recoveryTripping time delay for load de-energizing (trip) in case of all circuit voltage faultsWith DIP switches on the deviceâÂÂs front panel the user can select the type of circuit monitored 400 / 415V, and turn on/off monitoring of the following circuit parameters:Phase sequencePhase imbalance or asymmetryUnder voltageOver voltageMicrocontroller basedON/OFF delay timersover & under voltage2NO + 2NC RelaySales Package: device, user manualBrand: novatek electroModel Number: RNPP-311MModel Name: Three Phase Voltage Monitoring RelayCurrent Rating Range: 0-5 ANumber of Poles: 3Curve Characteristics: DigitalMounting Type: Vertical, HorizontalDIN Rail Mount Type: 35 mmStandard Approval: CE, ISO 9001:2015Visual Trip Indicator: YesSuitable For: Industrial, Hotel, Domestic, Three Phase MotorsPrevention Capability: NoOperating Time: 0.02 secOperating Voltage: 415 VOther Features: The front panel LEDs display the following:
