Woodward MFR-11/ G59

The MFR Series 1 is a family of microprocessor based protective relays that offer multiple protective features in a single package. Using a new digital procedure to measure rms values – enabling a high measuring accuracy – the MFR Series 1 is insensitive to harmonics, transients or disturbing pulses. The MFR– 11 is equipped with a DIN housing for front installation ( front protection IP 54) or for snap on rail installation. This simplifies the design of the switchgear cabinet, facilitates the commissioning, ensures that the operation of the system is user friendly and increases the overall availability of the system.
