Description

Product Introduction

ABB REF615 HBFJAEAGNDA6BAA11G is a feeder protection relay for utility and industrial MV distribution networks. It protects overhead lines and cable feeders in radial, looped, and meshed systems, with or without distributed generation.

This is configuration J, which adds overfrequency, underfrequency, and rate-of-frequency-change (ROCOF) protection to the standard overcurrent and earth-fault portfolio. It supports IEC 61850 Editions 1 and 2, GOOSE messaging, IEC 61850-9-2 LE, Modbus, DNP3, and IEC 60870-5-103. The withdrawable plug-in design speeds field swaps. 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 HBFJAEAGNDA6BAA11G.
• 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.
