MFR 15 Multi Function Relay Protection & Control


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 the control to have a high measuring accuracy, regardless of harmonics, transients or disturbing pulses.

The MFR 15 model includes a synchronizer and a load (kW) and power factor (cosphi) controller via discrete outputs to combine protection and control into one unit. The SNY-I package offers additional functionality. It has kW load sharing capability for multiple unit applications.

The compact size and multiple functions of the MFR 15 help to simplify switchgear design. The digital display offers a user-friendly interface to setup the unit as well as monitor the operation and display any alarms.
