Shelly PRO 3EM RC 2000A three-phase, high-performance professional Wi-Fi + Ethernet energy meter with 3 x 2000A Rogowski coils

The Shelly PRO 3EM RC 2000A version is Shelly’s smart energy meter for DIN rail mounting in electrical cabinets, supporting Wi-Fi + Bluetooth + Ethernet + Modbus, and capable of three-phase, bidirectional measurement (consumption and feed-in). Thanks to its LAN connectivity, it can be installed in locations where Wi-Fi reception is severely limited (e.g. due to metal cabinets). The product includes three pieces of 2000A Rogowski coils.

Shelly Pro 3EM RC – Smart Three-Phase Energy Meter with Rogowski Coils

The Shelly Pro 3EM RC is a professional smart energy meter suitable for industrial use, capable of connecting three Rogowski coils (contactless current measurement). It is ideal for detailed monitoring of energy consumption in small and medium-sized enterprises, whether for entire buildings or individual systems.


Main features:

  • Maximum measurement range: up to 2000 A per phase
  • 4-quadrant measurement: precise tracking of active, reactive, import, and export energy
  • DIN rail mountable design
  • Multiple wiring options: suitable for both single-phase and three-phase systems
  • Rogowski coil current sensing: contactless, quick, and safe installation
  • Phase sequence error detection: optionally enabled, detects A-B-C sequence errors based on zero crossings
  • Per-channel calibration: precision adjustment possible with at least 500 W load
  • Load threshold detection: no energy is added to statistics below 30 VA, and the user receives a warning
  • Optical pulse indication: real-time energy usage is visibly trackable
  • Real-time clock (RTC): stores precise timestamps even when the internet connection is lost
  • Data logging: stores up to 60 days of consumption data on the device
  • External contactor control: automated or script-controlled load switching is possible using the Shelly 3EM Switch Add-on
  • Accuracy class: Class B (according to IEC 62053-21)


Communication and integration:

  • Local and remote access: operates standalone on Wi-Fi networks but can also be accessed and controlled remotely via the internet
  • Built-in web interface: configuration, monitoring, and control directly from a browser
  • MQTT(s) support: easy integration into BMS and HMI systems


Applications:

  • Monitoring power consumption in industrial facilities
  • Energy efficiency analysis for SME building operations
  • Contactless measurement without dismantling existing systems
  • Automated energy-based control systems
