Primary Wound Current Transformer Model 189
Primary Wound Current Transformers generally used for ammeters and wattmeters. The primary winding is wound directly on the core, making these ideal for low primary current applications where a bus-bar primary cannot be used. 600V, 10 kV BIL Full Wave, CSA and UL Recognized.
