DEIF MVR-F255 Directional Feeder Protection

The MVR-F255 feeder protection relay offers directional feeder protection

for applications which require a large I/O capacity and most comprehensive

protection functionality including advanced communication.

The MVR-F255 feeder protection relay was developed for application which

require a most comprehensive functionality for feeder protection and a large

capcity of I/Os. The device supports IEC 61850 communication.

With 11 available extension slots the device is best equipped for most complex

feeder applications.
