Transformers with build-in measuring transformers

Categories:
TC_CV transformers with build-in measuring transformers, with bus-bar, either for cable or for plate. Their enclosure is made of plastic. The TC_CV Transformers have different transformation ratios, for primary 10A to 600A and secondary at 1A. Output 4-20mA.
