TA30R Transformer

Description: The TA30R open core current transformer for measuring instrumentation. Is a transformer for bus-bar primary, for cable or bus-bar of different dimensions. The casing is made of resin and its main advantage is the ease installation due to the possibility of opening the core. Is more robust because is encapsulated in resin, allowing the installation even outdoors.

The TA30R transformer have different transformation ratios, for primary ones from 100 A to 400 A, and secondary ones at 1A or 5A. The accuracy classes can be 0.5, 1 y 3 according to the IEC 61869-2 standard.
