TU3AP Transformer

Description: Current transformer TU3AP for measurement instrumentation. They are transformers with primary winding for low currents. The casing is made of plastic and have the possibility of being filled with resin for installation in more hostile environments. The connections of the primary can be for cable or for bus-bar.

The TU3AP have different transformation ratios, for primary ones from 5 A to 400 A and secondary 1 A or 5 A. The accuracy classes can be 0.5 or 1 according to the IEC 61869-2 standard.
