Product Introduction & Supply Chain Strategy
The ABB REF610C11HCNR01 is a digital feeder protection relay designed for medium-voltage distribution networks. It combines protection, monitoring, event recording, measurement, and communication into a compact Intelligent Electronic Device (IED), helping safeguard feeders against overloads, short circuits, and earth faults.
Purchasing the REF610C11HCNR01 as New Original / New Surplus supports long-term reliability while reducing lifecycle risk. Since protection relays are essential for maintaining power system availability, keeping one or two units as buffer stock minimizes lead time variability, supports last-time-buy planning for legacy installations, and lowers Total Cost of Ownership (TCO) by avoiding prolonged outages.

Installation & Configuration Guide
Stage 1 – Pre-Installation (Prep & Safety)
- Apply Lock-Out/Tag-Out procedures.
- Verify the complete model number .
- Wear a grounded ESD wrist strap.
- Back up all protection settings using ABB configuration software.
- Record:
- Firmware revision
- CT ratio settings
- Protection parameters
- Communication configuration
- Relay logic
- Photograph all terminal wiring.
Stage 2 – Removal
- Isolate auxiliary power.
- Disconnect CT, trip, alarm, and communication wiring.
- Label all terminal connections.
- Remove mounting hardware.
- Carefully withdraw the relay.
- Inspect terminal blocks before installing the replacement.
Stage 3 – Installation (Clone & Seat)
- Confirm hardware revision and model number.
- Install the relay securely in the panel.
- Reconnect all CT, digital I/O, and communication wiring.
- Restore the saved protection settings.
- Verify grounding.
- Confirm wiring against project documentation.
Stage 4 – Power-On & Testing
- Apply auxiliary power.
- Verify normal startup and self-diagnostics.
- Confirm communication with SCADA.
- Perform secondary injection testing.
- Verify trip outputs and alarm functions.
- Return the feeder to service after successful functional verification.
Firmware/Software Versions & Upgrade Notes
- Verify the installed firmware revision before replacing the relay.
- Back up all protection settings and disturbance records before removal.
- Match firmware versions whenever possible to maintain compatibility with the existing protection scheme.
- Avoid firmware upgrades during emergency maintenance unless specifically required.
- After installation, verify CT ratio settings, communication protocols, and event recording functions before commissioning.
Frequently Asked Questions (FAQ)
1. Is this a genuine ABB product?
Yes. This relay is supplied as New Original / New Surplus. It is not refurbished, repaired, or removed from a decommissioned installation.
2. Why is New Surplus priced higher than refurbished relays?
New Surplus units retain original OEM manufacturing quality and full component life expectancy. Refurbished relays may contain aging power supplies, relay contacts, or electronic components that can increase long-term maintenance risk.
3. What applications use the ?
The is designed for medium-voltage feeder protection in industrial plants, substations, utility distribution systems, and commercial power networks. It provides protection, monitoring, measurement, and communication for feeder circuits.
4. Can this relay be replaced while the feeder remains energized?
No. Protection relay replacement should only be performed after the circuit has been safely isolated and all site electrical safety procedures have been completed.
5. Will replacing the relay erase the protection settings?
A replacement relay requires the original configuration to be restored. Always back up protection settings, communication parameters, and event records before removing the existing relay.
6. What quality inspections are completed before shipment?
Each New Original / New Surplus relay typically undergoes:
- OEM part number verification
- Serial number inspection
- Visual hardware inspection
- Terminal and connector verification
- ESD-safe handling and packaging
- Functional verification where applicable
7. What warranty is typically provided?
A 12-month warranty is commonly offered for New Original / New Surplus protection relays, providing dependable support for critical power system maintenance and asset management.
