MFR 1

The MFR 1 Series is a family of industrial grade protective relays that offer multiple protective features in a single package.
Using a digital processor to measure true RMS values enables a high degree of measuring accuracy regardless of harmonics, transients or disturbing pulses.

MFR 13

The MFR 13 model is a complete generator protection unit packaged into one compact device. Typical applications are generators and switchgear equipment that require independent protection architecture. Different packages offer additional functionality.

Common Features:

• True RMS generator voltage measurement
• True RMS generator current measurement
• kWh metering
• Configurable trip/control set points
• Configurable delays for each alarm
• Two-line Liquid Crystal display
• Operation and alarm indication
• Display of measured values
• English/German display language
• PC and front panel configurable

Common Protection Functions:

• Over-/undervoltage (ANSI# 59/27)
• Over-/underfrequency (ANSI# 81O/U)
• Voltage assymetry (ANSI# 47)
• Zero voltage monitoring
• Overload (ANSI# 32)
• Reverse power (ANSI# 32R)
• Reduced power (ANSI# 32F)
• Unbalanced load (ANSI# 46)
• Reactive power
• Loss of excitation (ANSI# 40Q)
• Independent time-overcurrent (ANSI# 50/51)
• Inverse time-overcurrent (IEC 255)
• Inverse time-overcurrent with voltage restraint (ANSI# 51V)

MFR 13/GP Features:

• 3 configurable relays
• Ground fault (calculated) protection (ANSI# 50GS/51GS)
