Product Description





Applications and Definition
TR-BH and TR-SDH series current transformers are used in the protection test of GCS low-voltage pull-out switchgear and domino combined switchgear as well as high-power electrical equipment. They are suitable for the measurement and protection of electric energy in ac circuits with rated voltage of 0.66kV blow and rated frequency of 50Hz and 60Hz. This type of transformer has the characteristics of low price and good quality, high performance index, flexible installation mode and strong applicability, etc., and can also be customized according to user requirements.

All series products are composed of the above two installation methods A and B, and the installation components are shipped by default.
