TUP_R measuring transformers

Current transformers for measurement instrumentation. They are usually installed on plates. lts envelope is made of resin which gives them greater robustness and possibility of installation in adverse environments.

Connections

Dimensions

Transformers have different transformation ratios, for primary ones from 500 to 5000 A and secondary ones at 1 A or 5 A. Precision classes can be 0.5 and 1 according to IEC 61869-2. Depending on the model and class, the power of the secondary load varies.
