Description
Product Introduction
Your substation feeder protection failed during a storm, and the replacement quote from ABB says 12–16 weeks. You need the ABB REF615 HBFFAEAGNBA1BNA11G now—this unit won’t wait on backorder.
This is a standard configuration G feeder IED built for compact MV switchgear with combi-sensor inputs. It delivers directional overcurrent and earth-fault protection, synchro-check, and circuit-breaker condition monitoring. Field deployments show trip times under 25 ms for instantaneous stages. This design choice is actually clever for space-constrained installations—though your mileage may vary depending on ambient temperature.
Installation & Configuration Guide
Phase 1—Pre-Installation (est. 10 min)
- Safety first: De-energize the bay, lockout/tagout, wait 5 min for discharge
- Tools needed: Fluke 115 multimeter, ESD wrist strap, torque screwdriver (0.5 N·m), camera
- Backup tasks: Export PCM600 program, photograph DIP switches (if applicable), wiring, and rack layout
Phase 2—Removal (est. 5 min)
- Label every wire before disconnecting—Photo. Photo. Photo.
- Release DIN rail latch, pull module perpendicular to backplane
- Inspect backplane connector pins for bent contacts or corrosion
Phase 3—Installation (est. 10 min)
- Put on ESD wrist strap + use ESD mat; dry winter conditions demand extra caution. I watched an engineer skip the strap in January. The module smoked on power-up. $2,000 gone.
- Verify part number matches HBFFAEAGNBA1BNA11G
- Replicate DIP/jumper config from your photos exactly; remember: 120 Ω termination resistor at bus ends only
- Seat until latch clicks, reconnect wiring (~0.5 N·m torque)
- Run pre-power checklist: no shorts, correct polarity, shield grounded
