AQ F215 - feeder protection IED

About product

AQ F215 offers a modular feeder protection and control solution for applications requiring both current and voltage based protections along with complete measurements. Up to three optional I/O or communication cards are available for more comphrehensive monitoring and control applications. The AQ F215 communicates using various protocols including IEC 61850 substation communication standard.
