AQ-F205 Feeder Protection Device
Home Protection relays Feeder protection & control AQ-F205 Feeder Protection Device
Description
AQ-F205 is suitable for any application that requires directional overcurrent and earth fault protections along with voltage and frequency protections. AQ-F205 comes with complementary measurement, monitoring, control and communication features. The relay’s standard configuration of eleven (11) digital inputs and ten (10) digital outputs along with a large, programmable HMI allow for a variety of adaptations.
Highlights:
Integrated protection, control, and measurement.
Price–performance ratio.
