BH-0.66 Ⅲ Type Current Transformer

Function and Use

The BH-0.66 III type current transformer is used indoors, with a maximum equipment voltage of 0.72kV or less, load power factor of 0.8, and rated frequency of 50Hz in AC circuits for current and energy measurement or metering. It is installed by busbar fixation or base plate fixation. The transformer has a window in the middle for busbar or cable passage. Compared with Type I and Type II, it has fewer accessories and is easier to install.
