TUC_ measuring transformers

TUC__ transformers for measuring instrumentation, with through primary, either for cable or for PCB. Their enclosure is made of plastic. TUC__ transformers have a transformation ratio for primary from 50A to 2500A and secondary in 1A or 5A. The accuracy can be 0.5, 1 and 3 according to IEC 61869-2.
