TUP20RC Transformer

Description: Current transformer TUP20RC for measurement instrumentation. Is a transformer for bus-bar primary, usually for bus-bar. The casing is made of resin which gives it greater robustness and possibility of installation in adverse environments.

The TUP20RC transformer have different transformation ratios, for primary ones from 500A to 1500A and secondary ones at 1A or 5A. Accuracy classes can be 0,5 or 1 according to the IEC 61869-2 standard.
