TUP20R Measuring Transformer

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

The TUP20R have different transformation ratios, for primary from 750 A to 2000 A and secondary ones at 1A or 5A. The accuracy class can be 0.5 according to the IEC 61869-2 standard.
