  • 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
