Industrial earth leakage protectionWG SeriesCBS-4 / CBS-4 CEarth leakage monitoring and signaling unitof the external transformer of the WG / WGCSeriesDescriptionFeatures}}Unit equivalent to 4 earth leakage protectionnetworks. 4 independent programmablerelays available}}Four inputs to connect the external toroidaltransformers of the WG}}Superimmunized Type A relay with highfrequency current filtering and high immunity.Monitoring in true root mean square (TRMS)}}Reduced size, with 3 modules}}5 independent programmable outputs(4 earth leakage trip relays and 1 pre-alarmtrip).ApplicationThe CBS-4 earth leakage unit associated tothe transformers of the WG / WGC Series allowsan 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.ProtectionNo. of protectionsClassMeasurementSensitivityDelayEarth leakage transformerTest and ResetAssociated circuit breakerLED indicatorDisplay View4 Independent linesA superimmunizedTrue root mean square (TRMS)0.03 A ... 30 ATime defined: 0,02 ... 10 sInverse curve: instantaneous or selectiveExternal, TRANSFORMERS WG/WGPWith built-in buttons, T & RContact or Circuit breaker + trigger coil• Power supply voltage• Leakage trip• Pre-alarm• Interlocked earth leakage self-reclosing• Current trip (red display when triggered)• Instantaneous leak level indicator in each channel• Parameter programming• State of the self-reclosing- Disconnected externaltrans. indicator- Automatic self-reclosing enabledFeaturesAuxiliary power supply230 Vac (± 20 %) 50 ... 60 HzOutput contacts250 Vac, 5 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 61008In addition, version CBS-4 C with RS-485communications is used with the PowerStudiosoftware, which allows the centralisedsupervision of the system in real time, witha record log that can be analysed later on.P1-20
