BH-0.66,SDH-0.66 type current transformerDetailed product description：

BH-0.66 current transformer is used for current and energy measurement and relay protection in indoor AC circuits with rated voltage of 660V and rated frequency of 50Hz.
SDH-0.66 current transformer is suitable for use in power systems with a rated frequency of 50Hz, rated voltage of 0.66kV, 0.69kV, 0.5kV and below for energy metering, current measurement and relay protection. This type of transformer is used for indoor distribution cabinets and boxes. The current transformer is a busbar type plastic shell insulation. The lower part of the product has an installation plate for fixed installation, and the middle window hole is used for the passage of the primary busbar.
