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.

- 5x Current input (configurable 0.2…10A)

- 4x Voltage input (1.00…480.00V (RMS)

- 11x Digital input

- 10x Output relay (4NO, 1CO)

- 1x IRF output (1CO)
