AQ F215 Feeder Protection Relay

AQ F215-AQ F215 Feeder Protection Relay

Sipariş No : AQ F215

AQ F215 offers a modular feeder protection and control solution for applications requiring both current and voltage based protections along with complete measurements of up to class 0.2S accuracy for power and energy. 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.
