Current transformer works as a low-power single-phase transformer, operating in a state close to a short circuit. Dedicated for higher currents measurement by measuring instruments with smaller measuring ranges (ratio 1: 1000). Technical data Test current: 0-10A (50Ohm) Ratio: 1: 1000 Insulation resistance: 4500V Dimensions: 18.3mm x 17mm https://elecena.pl/product/22614424/ac-current-sensor-5a-5ma-zmct103c-current-shunt 2023-02-22 https://elecena.pl/product/22614424/ac-current-sensor-5a-5ma-zmct103c-current-shunt 2025-10-29
