Application


REF 610 is a versatile multifunction protection relay mainly designed for protection of incoming and outgoing feeders in MV distribution substations. REF 610 can also be used as back-up protection for motors, transformers and generators, in industrial as well as in utility applications.

The large number of integrated protection functions, including three-stage overcurrent protection, two-stage, non-directional earth-fault protection as well as thermal protection, makes REF 610 a complete protection against overcurrent and earth faults.

The optional are protection for detection of are situations in air insulated metal-clad switchgears and the auto-reclose function for automatic clearing of overhead line faults increase the range of applications further.

The large number of digital inputs and output contacts allows a wide range of applications.
