Narrow Profile Transformers TU_PS

The TU__PS current transformer is used for measuring instrumentation. It is a transformer for through primary, either for cable or for plate and with different window sizes. Its enclosure is made of plastic and has a narrow profile, which allows a better adaptation in the panel due to its reduced dimensions. The TU_PS transformer has different transformation ratios, from 30A to 1000A. The accuracy is from 0.5 to 3 according to IEC 61869-2. This transformer is also available in special classes 0.5s, 0.2s and 0.2s.
