▼DIN-rail current transformerDIN-rail current transformer CT 35/1A and 64/1Awith voltage tapWhile measuring in substations, there are often problems regarding the space, as voltageand current are necessary for each phase. Those problems can be solved by usingthe DIN-rail CTs, which combine three functions in one device. The DIN-rail CTconsists of series terminal, current transformer and voltage tap with fuse. The fuse isdirectly mounted on the primary and therefore the non protected part of the measuringcable is very short, which ensures a high intrinsic safety.The DIN-rail CTs lead to simple wiring, low mounting costs and high reliability dueto less connections, retrenchment of space and rare connection errors.Technical dataGeneralsMaximum voltageInsulation voltageRated currentMaximum current (16 mm 2 )Protection class690V1890V / 50Hz 1min.67A76AEDimensional drawing72Protection IP 20Ambient temperatureHousing-5 .. +40°CPA, 30% glasScrew terminal Cross recess DIN 7962-H2Series terminalStandard IEC60947-7-1Connection diameter 1,5 bis 16 mm 2Voltage tapShort-circuit strength70kA at 400V; 50HzConnection diameter max. 4 mm 2FuseCurrent transformerCapacity5x25mm with indicating pin;max. 2A SIBA DIN 41576-2Standard IEC60044-160xIn/1s9296CT variantsCT ratio Class Power Item number35/1A 1 0.2VA 15.03.00264/1A 0,5 0.2VA 15.03.003Connection diagram32All dimensions stated inthese drawings are in mm.172
