REF610 is a member of ABB’s Relion® product family and part of its 610 product series.
The series includes protection relays for feeder protection, motor protection and general system voltage supervision.
The plug-in design facilitates the commissioning of the switchgear and enables fast and safe insertion and withdrawal of protection relay plug-in units.
REF610 is primarily intended for the protection of incoming and outgoing feeders in distribution substations of
resistance earthed and solidly earthed power systems.
REF610 is suitable for employment in marine and off-shore environments.
Supplied with an optional arc protection function REF610 also provides fast substation busbar arc-fault protection.
Application
REF610 is a versatile multifunction protection relay mainly designed for protection
of incoming and outgoing feeders in MV distribution substations.
The relay 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 the relay a complete protection against overcurrent and earth faults.
The optional arc protection for detection of arc 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.
