ABB REF615E_1G Feeder Protection Relay — Complete Product Guide
The ABB REF615E_1G Feeder Protection Relay is a sophisticated numerical protection relay from ABB’s Relion 615 series, specifically designed for feeder protection in medium voltage distribution networks on marine vessels and industrial power systems. The ABB REF615 provides comprehensive overcurrent, earth fault, frequency, and breaker failure protection — making it a critical safety component in marine switchboards, power distribution panels, and industrial MV networks worldwide.
🔧 How It Works
The ABB REF615E_1G Feeder Protection Relay continuously monitors current and voltage inputs from CTs and VTs connected to the protected feeder. When a fault condition — such as overcurrent, directional earth fault, or frequency deviation — is detected, the relay sends a trip signal to the associated circuit breaker within milliseconds, isolating the faulted section and protecting the connected equipment and distribution network.
The relay features a built-in LCD display with keypad navigation for local configuration and monitoring, LED indicators for protection function status (Overcurrent, Dir. Earth Fault, Combined Protection, Frequency, Breaker Failure, CB Condition Monitoring, Supervision), and both front-panel RJ45 and rear communication ports for SCADA integration via IEC 61850, MODBUS, or DNP3 protocols. The unit is fully configurable via ABB’s PCM600 software tool, allowing engineers to customize protection settings, logic, and communication parameters to suit the specific network requirements.

🚢 Where Is It Used?
- Marine vessel medium voltage switchboards and distribution panels
- Offshore platform power distribution and feeder protection
- Industrial MV networks — factories, power plants, substations
- Ship generator feeder protection on cargo vessels and tankers
- Direct replacement for existing ABB REF615 installations
- Any application requiring IEC 61850 compliant feeder protection
⚠️ How To Check If REF615E_1G Is Faulty
- Apply auxiliary voltage (48–250 VDC or 100–240 VAC) to the relay power terminals
- Verify the LCD display illuminates and shows the relay status screen — “Ready” LED should be green
- Using ABB PCM600 software, connect via front RJ45 port and verify communication is established
- Check all protection function LEDs on the front panel — none should be permanently illuminated without a real fault condition
- Inject test current via secondary injection test set to each current input and verify the relay measures correctly
- Verify trip output contacts operate correctly by injecting fault current above the set overcurrent threshold
- If display is blank or relay does not power up, check auxiliary power supply voltage and fuse
- If “Supervision” LED is permanently on, relay has detected an internal self-check failure — check event log via PCM600
