Smart earth leakage protection - Circutor

Industrial earth leakage protectionWGBUTransformer with built-in earth leakage relayDescriptionFeaturesThe WGBU Series is a compact earth leakageprotection system. It is composed of atoroidal transformer with a built-in earth leakagerelay.}}Multi-range electronic relay• yThe sensitivity can be adjusted to 0.03 ... 3 A• yTrigger delay of 0.02 ... 1 ws, adjustable}}Type A relay with high frequency currentfiltering and high immunity. Monitoring in trueroot mean square (TRMS).}}LED indicators:• yGrid connection LED• yPre-alarm and trigger LED: 1 flash every2 s, leak between 25 and 50 % of the sensitivityselected; 1 flash every 1 s, leak between50 and 75 % of the sensitivity selected;1 flash every 0.5 s, leak exceeding 75% of the sensitivity selected; permanentlylit, trigger of the earth leakage protection.ApplicationThe WGBU series offers a reliable earthleakage protection, with simpler cabling andsavings in the assembly time. In addition, installationis very simple, thanks to its compactdimensions.Earth leakageClassMeasurementSensitivityDelayEarth leakage transformerTest and ResetAssociated circuit breakerLED indicatorRemote Control (inputs)Circuit breaker controlProtectionA superimmunizedTrue root mean square (TRMS)0.03 ... 3 A0.02 ... 1 sBuilt-in transformers of the WGWith built-in buttons, T & RContact or Circuit breaker + trigger coil• Power supply voltage• Trip due to leakage• Pre-alarmExternal Test OptionThrough an NO/NC switched relay, dependingon the connection with the circuit breakerFeaturesAuxiliary power supply230 Vac (± 20 %) 50 / 60 HzOutput contacts250 Vac, 6 AOperating temperature -10 ... +50 ºCConstruction featuresFixingDIN Panel / RailDimensionsDepending on the typeWeightDepending on the typeDegree of protectionIP 20 Terminals, IP 41 back panelStandardsIEC 60947-2, IEC 60755, IEC 62020, IEC 61008P1-27
