Product Introduction
ABB REF615C_C HCFFAEAGANB2BAN1XC Product Introduction
ABB REF615C_C HCFFAEAGANB2BAN1XC is a Relion 615 series feeder protection and control relay designed for medium-voltage distribution networks. It combines electrical protection, breaker control, measurement, event recording, and substation communication functions inside a single IED platform.
The main value of ABB REF615C_C HCFFAEAGANB2BAN1XC is maintaining established feeder protection schemes where IEC 61850 integration, relay coordination, and configuration continuity are critical. Before replacement, verify the complete ordering code, PCM600 project file, communication settings, CT/PT configuration, and protection parameters.

Application Scenarios & Field Pitfalls (The Engineer’s Perspective)
Engineering Pain Point
A medium-voltage feeder trips unexpectedly during normal operation. The breaker operates correctly, but the protection relay event record shows unclear fault information or communication with SCADA is lost.
This is where relay replacement becomes more than a hardware swap. Protection settings, IEC 61850 engineering files, and I/O mapping determine whether the replacement unit returns the feeder to service correctly.
Typical Applications
- Electrical Substations – Medium-voltage feeder protection, breaker control, and fault recording.
- Industrial Plants – Factory power distribution systems protecting motors, transformers, and process feeders.
- Renewable Energy Facilities – Collector feeder protection and grid interconnection monitoring.
- Utility Distribution Networks – Overhead line and cable feeder protection with remote supervision.
Technical Pitfalls to Avoid
- Do Not Ignore the Full Ordering Code
The REF615 family includes many hardware configurations. The suffix defines I/O quantity, communication options, and measurement capability. Confirm the exact code before installation. - Restore PCM600 Configuration Correctly
The relay hardware alone does not contain the complete protection engineering. Restore the correct parameter file, logic configuration, communication settings, and IEC 61850 configuration. - Verify CT/PT Settings Before Energization
Incorrect transformer ratios or polarity settings can cause incorrect measurements and unwanted trips. Perform secondary injection testing before returning the feeder to operation.
