AQ-F210 Feeder Protection IED

The AQ-F210 offers a modular feeder protection and control solution for non-directional overcurrent and earth-fault protection with automatic reclosing. Up to four optional I/O or communication cards are available for more comprehensive monitoring and control applications. The AQ-F210 communicates using various protocols including IEC 61850 substation communication standard.

Highlights

  • Cable end differential protection
  • Low-impedance REF protection
  • Harmonics protection and control
  • 5-shot scheme controlled autorecloser
