TU_R_ Measuring transformers. Narrow profile – Horizontal Bus-Bar

Categories:
Current transformers for measurement instrumentation. Bus-bar transformers made of resin, which gives them a special robustness. They have a narrow profile which allows a better adaptation in the frame due to its small dimensions. The placement of the plate can be done horizontally due to the position of the terminals of the secondary.
