TU20PS-3 Transformer

Description: Current transformer TU20PS-3 for measurement instrumentation, designed for three-phase systems. Is a transformer for primary through, either for cable or for plate. The envelope is plastic. It have a narrow profile, and have the three phases in the same equipment they allow a better adaptation in the frame due to small dimensions.

The TU20PS-3 have differnt transformation ratios, for primary ones from 30 A to 250A and secondary ones at 1 A or 5 A. The accuracy classes can be 0.5, 1 or 3 according to the IEC 61869-2 standard
