Detail 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.
