Description
ABB REF615C_D (HCFFAEAGABC2DAA1XD) – Feeder Protection & Control Relay for MV Distribution
The ABB REF615C_D is part of the Relion 615 series, designed for primary and secondary distribution feeder protection. It’s a compact IEC 61850 IED that typically covers overcurrent, earth-fault, breaker failure, and basic control/automation in one unit. The long code “HCFFAEAGABC2DAA1XD” is the factory configuration string—defining power supply, I/O mix, communication options, and accessories—so you get a pre-configured relay that drops neatly into switchgear projects with minimal engineering time.

Key Features
- Dedicated feeder protection: Overcurrent (50/51), earth fault (50N/51N), thermal overload, breaker failure, and autoreclose in a compact unit.
- IEC 61850 at the core: GOOSE messaging and station bus integration typically reduce hardwiring and commissioning time.
- Multi-protocol flexibility: In many cases supports IEC 60870-5-103, Modbus, and DNP3 in addition to IEC 61850 for brownfield compatibility.
- Rich I/O and measurements: 3-phase CT inputs plus residual current; VT inputs on selected variants for directional/voltage-driven logic.
- Breaker control & supervision: Local/remote control, SOE recording, trip circuit supervision—handy for maintenance and fault analysis.
- PCM600 engineering: Parameterization, logic, and firmware handling in a standardized ABB toolchain—engineers usually find the workflow predictable.
- Cyber and reliability options: User management, event logs, and time sync (SNTP/IRIG-B on selected builds) to keep records clean and traceable.
- Compact panel footprint: Flush mounting form-factor suits ring main units and metal-clad switchgear where door space is tight.
Technical Specifications
| Brand / Model | ABB REF615C_D – Order code: HCFFAEAGABC2DAA1XD |
| HS Code | 8536.49 (Relays, for a voltage > 60 V) |
| Power Requirements | Auxiliary supply typically 80–265 V AC/DC (wide-range). Some variants support 24–60 V DC. Please match to the exact order code before wiring. |
| Dimensions & Weight | 4U flush-mount case; typical depth ~160–200 mm; approx. 3–4 kg depending on options. |
| Operating Temperature | –40 to +55 °C (typical for Relion 615 series) |
| Signal I/O Types | 3× phase CT (1 A/5 A), 1× residual current; VT inputs on selected builds; multiple binary inputs/outputs (mapping varies by order code). |
| Communication Interfaces | Ethernet 10/100BASE-TX (RJ‑45) and/or fiber on selected options; front service port (USB) for PCM600; protocols typically include IEC 61850 (GOOSE), Modbus, IEC 60870‑5‑103, and DNP3 (per configuration). |
| Installation Method | Panel flush mounting on switchgear door/panel; rear terminal blocks; earthing via dedicated terminals; wiring per ABB drawings. |
Note: The option string HCFFAEAGABC2DAA1XD defines the exact I/O mix, PSU, and protocol set. From my experience, confirming this string against the single-line diagram before ordering avoids change orders onsite.
Application Fields
- MV feeders in primary and secondary substations (metal-clad, air-insulated switchgear)
- Ring main units (compact footprints where integrated control is preferred)
- Industrial distribution (mining, oil & gas, chemical plants) needing fast fault clearance
- Renewable collector feeders and small IPP substations with mixed protocols
- Utility network modernization where IEC 61850 GOOSE can reduce copper wiring
One thing I appreciate is how quickly commissioning teams hook this into an IEC 61850 station bus and get breaker control plus SOE without reworking panels. A maintenance supervisor recently told us the event logs and GOOSE diagnostics “saved an extra shutdown” during a feeder protection upgrade.
Advantages & Value
- Reliability: Robust protection algorithms and breaker supervision reduce nuisance trips, which typically means fewer unplanned outages.
- Compatibility: Multi-protocol support eases integration with existing RTUs/SCADA—helpful in staged retrofit programs.
- Cost savings: IEC 61850 GOOSE often replaces inter-panel wiring, cutting installation hours and panel copper.
- Engineering efficiency: PCM600 templates, logical nodes, and clear HMI shorten parameterization and testing cycles.
- Lifecycle support: Firmware upgradability and readily available spares seem to keep O&M straightforward in most cases.
Installation & Maintenance
- Mounting & environment: Install in a clean, dry switchgear cabinet with adequate ventilation. Maintain clearance for rear cabling and avoid heat sources.
- Wiring practices: Use shielded twisted pairs for analog and high-EMI environments; segregate CT/VT leads from tripping circuits; verify CT polarity and burden.
- Grounding: Bond the relay’s protective earth to the cabinet earth bar; maintain consistent equipotential bonding.
- Time sync & comms: If using IEC 61850 GOOSE, set VLAN/priority and confirm time sync (SNTP or IRIG‑B if available) before protection testing.
- Routine maintenance: Annual functional test (trip, BI/BO, LEDs), clean front filter/faceplate, and back up settings with PCM600. Apply firmware updates during planned outages per ABB release notes.
- Safety: De-energize trip circuits and short CT secondaries before disconnection. Follow lockout/tagout procedures at all times.
Quality & Certifications
- Typically CE marked; RoHS compliant
- Manufactured under ISO 9001 quality systems
- Many variants carry UL/cUL listings for North American projects
- Manufacturer warranty as per ABB policy; our supply warranty: 365 days
