TU_R_ Measuring transformers. Narrow profile - Window-type
The window-type TU_R_ measuring transformers are designed to adapt to both cables and busbars, offering a variety of window size options. Their specific design allows them to be placed horizontally, while the terminal blocks, strategically located in each model, facilitate their assembly and connection.
Encapsulated in resin, these transformers stand out for their durability and resistance, making them a reliable long-term solution. In addition, their slim profile gives them small dimensions that guarantee perfect integration into electrical panels.
