AQ-F255 Feeder Protection Devices
The AQ-F255 feeder protection devices offer a modular feeder protection and control solution for applications that require a large I/O capacity. You can add up to 11 I/O or communication modules into the device for extensive monitoring and control applications. The AQ-F255 feeder protection device communicates using various protocols, including the IEC 61850 substation communication standard.
