The Shelly 400A Current transformers scale the largevalues of current to small, standardized values for measuring purposes. Theyprovide a secondary current that is accurately proportional to the currentflowing in its primary circuit. The current transformer presents a negligibleload to the primary circuit *Only compatible with Shelly Pro 3EM-400A. Features Snap-on, screwless mounting system
