Shelly 120A Current Transformer Clamp

Current transformers scale the large values of current to small standardized values for measuring purposes. They provide a secondary current that is accurately proportional to the current flowing in its primary circuit. The current transformer presents a negligible load to the primary circuit. 

The length of the CT clamps cables is 60 cm.
