Power Quality Monitoring

▼Chapter 6Current transformersDINCT64/1/1 – DIN rail current transformers“Deeper” measurements (sub-distributions or loads/individual output) are more andmore common in electrical installations. The nominal currents are, therefore, relativelylow (64, 32 or 16A), the space is restricted and the accuracy of the current transformermust be sufficient for the power measurement (minimum class 1). These characteristicsare often difficult to combine.The DINCT64/1/1 combines these characteristics in a single product. Due to the uniqueconstruction, no solder, crimp or clamp connections are required. The secondaryleads are 1 meter long.Technical dataTransmission ratio:64/1A (32/1A & 16/1A)Accuracy: Class 1Power:0.5VAI cth ; continuous limit current: 120%I th ; thermal limit current: 60xIn/1sFrequency:50HzSecondary lead diameter: 0.5mm 2Ambient temperature: 45°C max.Standard:IEC6000-44-1Material:PA6.6Item number: 15.02.849All dimensions stated inthis drawing are in mm.ApplicationsTransmission ratio 64/1A1 x loopNominal measurement current 64AMax measurement current 76ATransmission ratio 32/1A2 x loopNominal measurement current 32AMax measurement current 38APrimary leadPrimary leadTransmission ratio 16/1A4 x loopNominal measurement current 16AMax measurement current 19APrimary lead173
