Shelly CT 400A Split-Core Current Transformer for Pro 3EM Energy Meter The Shelly 400A CT PRO 3EM is used to measure the current for larger loads so that you can stay informed. Get all the information on current measurements directly on the Shelly Smart Control app. 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. *Compatible only with Shelly Pro 3EM-400A The Device is a split-core current transformer for the Shelly Pro 3EM energy meter Snap-on, screwless mounting system Secondary winding high voltage protection Benefits: The current transformer scales the large values of current to small, standardized values for measuring purposes.
