## Description

RNPP-302 numeric voltage monitoring relay is designed for protection of three phase loads against major type of mains faults, 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 asymmetryContactor output side monitoring â full phase switching, contactor healthThe device performs monitoring the main circuit parameters and de-energizes (trips) load when the parameters fall beyond specified boundaries.The three digit, seven segment LED display on the relay front panel allows to:Continuously indicate the true RMS circuit voltage â phase voltage or line voltageIndicate type of occurring faultView (visualize) settings of modes and programming parametersMicrocontroller basedON/OFF delay timersover & under voltagePotential free relaySales Package: device, user manualBrand: novatek electroModel Number: RNPP-302Model 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 VAlarm Switch: YesOther Features: Digital input to turn ON/OFF the RNPP-302 remotely (emergency stop);
