Instrument transformers. Narrow profile TU_R
The current transformer TU__R for measuring instrumentation. It is a transformer for through-plate primary. Its enclosure is made of resin, which gives it a special robustness and it has a narrow profile which allows a better adaptation in the panel due to its reduced dimensions.
