Industrial earth leakage protectionWG SeriesCBS-8Earth leakage monitoring and signaling unitof the external transformer of the WG / WGPSeriesDescriptionFeatures}}Unit equivalent to 8 earth leakage protectionnetworks. 8 independent programmablerelays available}}8 inputs to connect the external toroidaltransformers of the WG / WGP}}Superimmunized Type A relay with highfrequency current filtering and high immunity.Monitoring in true root mean square (TRMS)}}Size adapted for 8 modules}}9 independent programmable outputs(8 earth leakage trip relays and 1 pre-alarmtrip).ApplicationThe CBS-8 earth leakage station associatedto the transformers of the WG / WGP Seriesallows an smart earth leakage protection. Itsdesign features guarantee maximum securityand continuity 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, RS-485 communications areused with the Power Studio software, whichallows the centralised supervision of the systemin real time, with a record log that can beanalysed later on.ProtectionNo. of protectionsClassMeasurementSensitivityDelayEarth leakage transformerTest and ResetAssociated circuit breaker8 Independent linesA superimmunizedTrue root mean square (TRMS)0.03 A ... 6.3 A external transformers WG / WGS0.03 A ... 63 A external transformers WGP/WGSPTime defined: 0,02 ... 10 sInverse curve: instantaneous or selectiveExternal, TRANSFORMERS WG / WGPWith built-in buttons, T & RContact or Circuit breaker + trigger coilSelf-reclosingNo. of reclosures 0 Programming option ... 10Time between reclosures0 Programming option ... 900 sPartial counter reset timeDouble the reclosing time• Power supply voltage• Leakage tripLED indicator• Pre-alarm• Interlocked earth leakage reclosing• Automatic self-reclosing enabled• Instantaneous leak level indicator in each channelDisplay View• Parameter programming• Self-reclosing statusFeaturesAuxiliary power supply230 Vac (± 20 %) 50 ... 60 HzOutput contacts250 Vac, 5 AOperating temperature -10 ... +50 ºCConstruction featuresFixing DIN Rail 46277 (EN 50022)Dimensions8 modulesWeight609 gDegree of protectionIP 20 Terminals, IP 41 back panelStandardsIEC 60947-2, IEC 60755, IEC 62020, IEC 61008P1-22
