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.
