TU3BP transformer

Description: Current transformer TU3BP for measurement instrumentation. Is a transformer 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 TU3BP have different transformation ratios, for primary ones from 5A to 600 A and secondary ones at 1A or 5 A. The accuracy classes can be 0.5 or 1 according to the IEC 61869-2 standard.
