TUC_ Measuring Transformers

Description: Current transformer TUC__ for measurement instrumentation. Is a transformer for wound primary, either for cable or for bus-bar. The casing is made of plastic.

Connections

Dimensions

The TUC_ transformer have different transformation ratios, for primary ones from 50A to 2500A and secondary ones at 1A or 5A. Accuracy classes can be 0,5, 1 or 3 according to IEC 61869-2 standard.

The transformer have a wider profile, which alolows to obtain a greater load power. Is an equipment indicated for applications in which the measuring instruments have a higher consumption.
