TU40PS Transformer

Description: Current transformer TU40PS for measurement instrumentation. They are transformers for primary through, either for cable or for bus-bar and with different window sizes. Its casing is made of plastic, and have a narrow profile, which allows a better adaptation in the frame due to its small dimensions.

The TU40PS transformer have different transformation ratios, for primary ones from 150 A to 800 A and secondary ones at 1A or 5A. The accuracy classes can be 0.5 or 1 according to the IEC 61869-2 standard.
