The AKH-0.66/III series adopts a vertical square-hole structure designed to accommodate 1–3 busbars. Four models are available: 60III, 80III, 100III and 130III, covering primary current ratings from 200A to 5000A, with 5A or 1A secondary output and Class 0.2 or Class 0.5 accuracy depending on the selected current ratio. The series is intended for AC current measurement and electrical metering with energy meters and measuring instruments. It meets the requirements of GB/T 20840.2-2014, equivalent to IEC 61869-2:2012, MOD.
