novatek electro Three Phase Voltage Monitoring Relay RNPP-302 MCB(3)

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); Changeover relay output (NO+NC): 8A 250VAC at cos φ=1 for the operation by the magnetic contactor to commutate any desired power load; Normally Open relay contact: 8A 250V at cos φ=1 for signalization/annunciation; Measurement accuracy for tripping thresholds: not exceeding 3V; Rated phase/line voltage: 220/380V, 230/400V or 240/415V selectable; Rated power consumption:not exceeding 5W; Protection degree of the enclosure case: IP40; Protection degree of terminal block: IP20; Operational temperature range from – 35 to +55°C and exposed to not more than 90% of relative humidity Weight not more than 0.3 kg Mounting: fit the standard 35 mm DIN-rail Mounting position: arbitrary – as per requirement RNPP-302 complies with requirements: IEC 60947-1:2004; ІEC 60947-6-2:1992; CISPR 11:2004; IEC 61000-4-2:2001.Width: 70 cmHeight: 86 cmWeight: 300 gWarranty Summary: 3 years limited manufacturing warrantyCovered in Warranty: manufacturing defects onlyNot Covered in Warranty: improper installation, physical damage and burning is not covered under warrantyWarranty Service Type: manufacturer carry in warranty
