The ABB REF615 HBFFAEAGNBA1ANB1XD is a high-performance feeder protection and control relay from ABB’s Relion 615 series, designed for medium-voltage distribution systems. The ABB REF615 HBFFAEAGNBA1ANB1XD integrates protection, control, monitoring, and communication into a single intelligent electronic device (IED), making it suitable for substations, industrial plants, and renewable energy systems.

The ABB REF615 HBFFAEAGNBA1ANB1XD supports advanced digital substation functions, including IEC 61850 communication and real-time data exchange, enabling seamless integration with SCADA and automation systems. 

In a medium-voltage distribution substation, the ABB REF615 HBFFAEAGNBA1ANB1XD is installed in feeder panels:

Monitors current and voltage via CT-VT inputs

Detects faults such as short circuits and earth faults

Sends trip signals to circuit breakers within milliseconds

Records disturbance data for fault analysis

For example, in an industrial plant, the ABB REF615 HBFFAEAGNBA1ANB1XD can isolate faults quickly and reduce downtime, ensuring continuous production and system safety.
