MFR 13
Multi Function Relay
· Complete generator
Protection protection in one unit
· True RMS sensing
· Synch-check
APPLICATIONS DESCRIPTION (continued) · Discrete inputs for
enabling and remote
The MFR 1 Series is a family of industrial grade protective Protection (all) ANSI # control
relays that offer multiple protective features in a single · Over-/undervoltage (59/27)
package. · Over-/underfrequency (81O/U) · Programmable relay
· Voltage asymmetry (47) outputs
Using a digital processor to measure true RMS values · Zero voltage monitoring
enables the control to have a high measuring accuracy, · Overload (32) · PC and front panel
regardless of harmonics, transients or disturbing pulses. · Reverse power (32R) configurable
· Reduced power (32F)
The MFR 13 model is a complete generator protection · Unbalanced load (46)
· Microprocessor
unit packaged into one compact device. Typical · Reactive power technology for
applications are generators and switchgear equipment · Loss of excitation (40Q) accurate, repeatable
that require independent protection architecture. Different · Independent time-overcurrent (50/51) and reliable
packages offer additional functionality. · Inverse time-overcurrent (IEC255) operation
· Inverse time-overcurr. w. volt. restraint(51V)
The MFR 13/GP is for generator protection use while the · Programmable
MFR 13/GPX adds synch-check functionality for one Package GP threshold set-points
breaker. A MOD bus RTU Slave interface for · 3 configurable relays with individual time
communication is added for the MFR 13/GPX-I package. · Ground fault (calculated) #1 (50GS/51#2GS) delays
The compact size and multiple functions of the MFR 13 Package GPX · CE marked
help to simplify switchgear design. The digital display · 8 configurable relays
offers a user-friendly interface to setup the unit as well as · True RMS busbar voltage measuring · UL/cUL Listed
monitor the operation and display any alarms. · Synch-check
· GL Approval
Package GPX-I
DESCRIPTION Same as Package GPX, plus: MFR 13/GP
· RS-485 Modbus RTU Slave interface
Features (all) 52 off
#1 no GL approval
#2 not according to ANSI guidelines
(three-step protection instead of inverse time characteristic)
