TU_PS-3 Triple narrow-profile transformers

Categories:
TU_PS-3 current transformers for measurement instrumentation, designed for three-phase systems. They are transformers for primary through, for cable and with different window sizes, their envelope is plastic. They have a narrow profile, and as they have the three phases in the same equipment they allow a better adaptation in the frame due to its small dimensions.
