Description
Product Introduction
ABB REF615 HBFBAAFANAC6BBA11G is a feeder protection relay for utility and industrial MV distribution. It protects overhead lines and cable feeders in radial, looped, and meshed networks, with or without distributed generation.
This relay supports overcurrent, earth-fault, overfrequency/underfrequency protection, and generator thermal monitoring (stator temperature, winding humidity, speed). It supports IEC 61850-9-2LE raw data transfer, Modbus TCP, DNP3.0, and GOOSE/MMS. The withdrawable plug-in design makes field swaps fast. Honestly, that cuts commissioning time when you’re under live-line pressure.
Installation & Configuration Guide
Phase 1—Pre-Installation (est. 10 min)
- De-energize the bay. Lockout/tagout.
- Wait 5 min for discharge.
- Export the existing relay program from PCM600.
- Photograph DIP switches, wiring, and rack layout.
- Tools: Fluke 115 multimeter, ESD wrist strap, torque driver (0.5 N·m), label tags.
Phase 2—Removal (est. 5 min)
- Label wires before disconnecting.
- Release the DIN rail latch.
- Pull the unit perpendicular to the backplane.
- Inspect backplane connector pins for bent contacts or corrosion.
Phase 3—Installation (est. 10 min)
- Put ESD protection on first. Wrist strap + ESD mat.
- Verify part number HBFBAAFANAC6BBA11G.
- Replicate jumper and terminal settings from photos.
- Seat the module until the latch clicks.
- Reconnect wiring at about 0.5 N·m.
- Check shield grounding against the wiring diagram.
