Triple narrow-profile transformers TU_PS-3

The TU__PS-3 current transformer for measuring instrumentation is designed for three-phase systems. It is for through primary, either cable or plate. Its enclosure is made of plastic. They have a narrow profile, and as they have the three phases in the same unit, they allow a better adaptation in the panel due to their reduced dimensions.
