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.
View MFR 1 series application overview
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)
