Applications

The REF610 is a multifunctional relay designed primarily for the protection

of incoming and outgoing lines in medium voltage distribution substations.

In industrial and utility applications, the relay can also be used as backup protection for motors,

transformers and generators.

The relay incorporates a number of protection features including three levels of overcurrent protection,

two levels of non-directional ground fault protection and thermal protection to provide comprehensive

overcurrent and ground fault protection.

An optional arc protection function can be used to detect arcing conditions in air-insulated metal-clad

switchgear,and an automatic reclosing function can be used to automatically clear overhead line faults.

These features further expand the range of applications for the relays.

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