Closed Type CT
AKH-0.66-I Series Low Voltage Closed Type Current Transformer
General
They are patented and flip designed. The appearance is nice and the wiring is convenient. The transparent polycarbonate material is selected for the flip.We can clearly see the secondary lead wiring. It have square-round hole for both cable and bus passing through . As alternating current signal acquisition element,it is generally matched with measuring instruments and widely used in electrical sets.
