Industrial earth leakage protectionWG SeriesRGU-10 / RGU-10 CElectronic earth leakage relay with externaltransformer of the WG / WGC SeriesDescriptionFeaturesElectronic earth leakage protection relay,used to connect to the earth leakage transformersWG / WGC Series}}Superimmunized Type A relay with highfrequency current filtering and high immunity}}Monitoring of the true root mean square(TRMS)}}Display of data on the screenTwo independentprogrammable outputs (main andpre-alarm)}}External input for remote control functions( 230 Vac).ApplicationThe RGU-10 relays associated to the transformersof the WG / WGC series allow ansmart earth leakage protection. Their designfeatures guarantee maximum security andcontinuity of the electrical service, avoidingunwanted tripping.Showing the value of the leak instantaneouslyon the display with the pre-alarm indicationsprovides the information about thestate of lines being protected, thus allowingthe implementation of an adequate preventivemaintenance approach.In addition, version RGU-10 C with RS-485communications is used with the Power Studiosoftware, which allows the centralisedsupervision of the system in real time, with arecord log that can be analysed later on.ProtectionClassMeasurementSensitivityDelayEarth leakage transformerTest and ResetRemote ControlAssociated circuit breakerLED indicatorDisplay ViewRemote signalingCircuit breaker controlFeaturesAuxiliary power supplyOutput contactsA superimmunizedTrue root mean square (TRMS)0.03 ... 3 A0.03 ... 30 A(PROGRAMMING)Time defined: 0,02 ... 10 sInverse curve: Instantaneous or selectiveExternal, TRANSFORMERS WG / WGCWith built-in buttons, T & RExternal Test OptionContact or Circuit breaker + trigger coil• Power supply voltage• Trip due to leakage• Disconnection of the external transformer• Pre-alarm• Current trip (red display when triggered)• Programming parameters• Instantaneous leakage current• Disconnection of the external transformer• Pre-alarm• Display of parameters with RS-485communications (RGU-10 C)Through an NO/NC switched relay, dependingon the connection with the circuit breaker230 Vac (± 20 %) 50 / 60 Hz(other values on demand)250 Vac, 6 AOperating temperature -10 ... +50 ºCConstruction featuresFixing DIN Rail 46277 (EN 50022)Dimensions3 modulesWeight236 gDegree of protectionIP 20 Terminals, IP 41 back panelStandardsIEC 60947-2, IEC 60755, IEC 62020, IEC 61008P1-18
