Next-generation DIN-mountable 3-Phase Energy Meter 

Shelly Pro 3EM-400 is a DIN rail mountable three-phase energy meter. Enhanced with all the gen2 firmware flexibility and LAN connectivity, it provides professional integrators with additional options for end-customer solutions. Shelly Pro 3EM-400 reports accumulated energy as well as instantaneous voltage, current, and power factor per phase in real-time.

  • Can measure up to 400 A for each phase and the neutral
  • 4 quadrant measurement with multiple connection types
  • Accuracy Class B active energy (Compliance with IEC 62053-21 based on manufacturer testing)
  • Photovoltaic ready
  • Phase sequence error detection (option)
  • Optical pulse indication of energy usage
  • Measurement accuracy tо 1%
  • Stores data in non-volatile memory that can be retrieved for a period of up to 60 days in 1-minute intervals
  • Package includes 3 pieces of 400 A Current Transformers
