Abb Ref 610 Protection Relay - China

ABB REF 610 Protection Relay INTRODUCTION 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-element overcurrent protection, two-element, non-directional ground-fault protection as well as thermal protection, makes REF 610 a complete protection against overcurrent and ground faults.
