The Shelly Pro 3EM 3CT 63 is a next-gen DIN rail-mountable energy meter for single or three-phase installations, featuring a 63A, 3-phase current transformer for non-contact measurements. It supports 4-quadrant measurement, optical pulse indication of energy usage, and is photovoltaic-ready. *It doesn’t have a built-in relay; contactor control requires a Shelly Pro Addon attached to the device.
Professional Smart Meter – Shelly Pro 3EM-3CT63 is a professional smart meter that reports accumulated energy, voltage, current, active, and apparent power per phase in real time. It stores data for up to 60 days in 1-minute intervals and includes a real-time clock to maintain accurate time if the SNTP server connection is lost.
Ideal for business energy measurement – In commercial buildings, it helps monitor energy usage across floors or departments allowing accurate cost allocation and identification of energy wastage. In manufacturing plants it tracks energy consumption of heavy machinery, optimizing usage to reduce operational costs. For store owners it monitors energy usage of systems like lighting, HVAC § refrigeration, helping to identify inefficiencies § reduce energy bills while supporting sustainable practices
