Description
ABB REF615A-1G_HAFNAEFCBGC1BQK11G – Compact Feeder Protection Relay for MV Distribution
The ABB REF615 series is purpose-built for medium-voltage feeder protection and control. This specific variant, REF615A-1G_HAFNAEFCBGC1BQK11G, is a factory-configured option of the Relion 615 platform. From my experience, it’s a solid fit for utility feeders, industrial substations, and RMUs where you want reliable overcurrent and earth-fault protection with straightforward IEC 61850 integration. You might notice that the device balances dependable protection functions with practical control, metering, and event recording—without being unnecessarily complicated for commissioning teams.

Key Features
- Feeder protection, ready to deploy – Typically includes time/instantaneous overcurrent (50/51) and earth-fault (50N/51N) functions, suitable for MV radial and ring networks.
- Integrated control and supervision – Breaker control, interlocking, and event/fault recording help operators act quickly and trace issues.
- IEC 61850 with GOOSE – Streamlines substation integration; peer-to-peer messaging reduces wiring and speeds up schemes like interlocking or bus transfer.
- Multiple I/O and analog inputs – CT inputs (1 A/5 A) and VT inputs, plus configurable binary I/O for trip, close, and status signals.
- Configurable logic – Practical logic elements make it easier to adapt to site-specific schemes without external relays.
- Ruggedized for substation environments – Designed for extended operating temperatures and electromagnetic immunity typical of MV switchgear rooms.
- Clear HMI and disturbance records – Local navigation is straightforward; disturbance files (COMTRADE) support root-cause analysis.
Technical Specifications

Application Fields
- Medium-voltage distribution feeders in utilities (radial and ring networks)
- Industrial substations and plant feeders for motors, process lines, and auxiliary loads
- Ring Main Units (RMUs) and compact switchgear where space is tight
- Campus, data center, and commercial MV systems that require IEC 61850-based integration
A maintenance supervisor told us their REF615 rollout “cut fault-finding time by half” because disturbance records and binary event logs lined up neatly with SCADA time stamps. That seems to be the common feedback when teams modernize legacy electromechanical relays.
Advantages & Value
- Reliability in harsh environments – Designed for MV switchgear conditions with strong EMC performance and robust I/O.
- Interoperability – IEC 61850 with GOOSE simplifies peer-to-peer schemes; Modbus/DNP3 help with brownfield SCADA.
- Lifecycle confidence – Part of ABB’s Relion family, which typically means solid firmware maturity and long-term parts support.
- Cost-effective deployment – Built-in logic and recording reduce add-ons; fewer auxiliary relays and wiring in many cases.
- Serviceability – Clear HMI, standard setting tools, and straightforward replacement strategies keep downtime low.
Installation & Maintenance
- Mounting – Install in a ventilated switchgear door or panel; observe half 19-inch, 6U cutout guidelines; maintain rear wiring clearance.
- Wiring – Use correctly rated CT/VT circuits; short CTs before handling; torque terminals per ABB guidance; ensure a clean protective earth.
- Commissioning – Verify CT/VT ratios, polarity, and phase rotation; run secondary injection tests; check GOOSE subscriptions and time sync.
- Environmental – Keep within the specified operating temperature; avoid condensation; provide dependable DC auxiliary supply with proper fusing.
- Routine maintenance – Periodically back up settings, download disturbance records, clean ventilation openings, and apply firmware updates as provided by ABB.
- Safety – Only qualified personnel should work on live panels; lockout/tagout procedures are essential during wiring or relay replacement.
Quality & Certifications
- CE compliant; RoHS compliant
- Manufactured under ISO 9001 quality systems
- UL/cUL practices commonly applied for North American projects (variant-dependent)
- Manufacturer’s support for firmware and lifecycle documentation
- Warranty: 365 days (our supply terms)
If you’d like, we can confirm the exact communication port type and I/O count coded by “HAFNAEFCBGC1BQK11G” against your network and protection scheme. In many cases, that small check saves time during FAT and site commissioning.
