MFR 11
Multi Function Relay
Protection
APPLICATIONS
The MFR 1 Series is a family of industrialgrade protective
relays that offer multipleprotective features in a single
package.
Using a digital processor to measure true
RMS values enables a high degree ofmeasuring accuracy regardless
ofharmonics, transients or disturbing pulses.
The MFR 11 model is a generator or mainsprotection unit packaged
into one compactdevice. Typical applications are generatorsand
switchgear equipment that requireindependent protection
architecture. Differentpackages offer additional functionality.
The MFR 11/MPis for mains protection usewith over-/undervoltage,
-frequency and
voltage asymmetry with 24 Vdc power supplywhile the MFR 11/NUhas
the samefunctions, but utilizes a wide-range powersupply.
The MFR 11/VDEWadds phase/vector jumpmonitoring to the MP
package. TheMFR 11/G59package adds df/dt (ROCOF)protection. The MFR
11/G59Nhas the samefeatures as the G59package, but utilizes
thewide-range power supply.
The MFR 11/SCis used for synch-check and
zero voltage detection to check whether twosystems are
synchronous or de-energized.
The compact size and multiple functions ofthe MFR 11 help to
simplify switchgeardesign. The digital display offers a
user-friendly interface to setup the unit as well asmonitor the
operation and display anyalarms.

The synchronizing voltage must be connected three-phase if the
measuring voltage is connected three-
phase (N not connected). If the measuring voltage is
connected four-phase (L1-L2-L3-N), the synchronizingvoltage may
be connected two-phase (L1-L2). L3 is
connected only for compensation and is not measured.
