REF611 is a dedicated feeder protection relay designed for the protection, control,
measurement and supervision of utility substations and industrial power systems.
The feeder protection relay REF611 can be supplied either with directional or non-directional overcurrent and earth-fault protection.
Directional earth-fault protection is mainly used in isolated neutral or compensated networks,
whereas the non-directional earth fault protection is intended for directly or low-impedance earthed neutral networks.
REF611 is a member of ABB’s Relion® product family and part of its 611 protection and control series of relays.
