Shelly 400A Current Transformer Pro 3EM

What is Shelly 400A Current Transformer Pro 3EM?

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.
