About the Shelly Current Transformer (split core) p/ Gen3 / Pro EM – 50A Precise current monitoring The Shelly Current Transformer (split core) allows you to accurately measure electrical current in single-phase or three-phase circuits up to 50A. It is compatible with Shelly EM Gen3 and Shelly Pro EM modules, ensuring that you can reliably track consumption in real-time. Technical specifications The transformer supports a nominal primary current of 50 A and provides a secondary current of 16.67 mA, with a transformation ratio of 3000:1 and an accuracy of ±1%. The dielectric strength is 3000 VAC, 1 mA for 60 seconds, and the load resistance is 20 Ω. The core is made of openable ferrite, the cable measures 60 cm, and the connector is a 2-pin Molex Micro-Fit type. It is fully compatible with Shelly EM Gen3 and Shelly Pro EM modules. Simple and secure installation Thanks to its openable ferrite core, 'clamp' type, you can install the transformer without interrupting the circuit. Its installation is quick and secure, making it ideal for residential, commercial, or industrial applications. Practical and versatile design The transformer features a 60 cm cable and a 2-pin Molex Micro-Fit connector, allowing for a direct connection compatible with your Shelly devices. The openable core easily accommodates any conductor up to 11 mm in diameter, making installation very convenient.
