DEIF MVR-F205 Directional Feeder Protection
MVR-F205
Directional Feeder Protection
The MVR-F205 feeder and earth fault protection relay is ideal for any application requiring directional overcurrent and earth fault protection.
The MVR-205 protection device comes with comprehensive measuring, monitoring and communication features. Its standard configuration provides additional digital inputs and outputs compared to the basic variant.
