DEIF MVR-F255 Directional Feeder Protection
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.
