Description
Model Suffix & Revision Decoder
The alphanumeric configuration REF610C11HCR01 represents a precise hardware and firmware build option from the factory:
- REF610: Base Feeder Protection Terminal Platform
- C: Non-directional phase overcurrent, earth-fault protection, and integrated non-volatile fault disturbance recorder core
- 1: Standard phase current transformer inputs ($1\text{ A} / 5\text{ A}$ software/hardware selectable)
- 1: Standard residual ground/earth current input ($1\text{ A} / 5\text{ A}$ software/hardware selectable)
- H: High-voltage universal power supply module ($110\text{–}240\text{ VAC/VDC}$ nominal operating window)
- C: Rear communication bus capability (supporting Modbus RTU, SPA-bus, or IEC 60870-5-103 serial loops)
- R01: Dedicated customer-specific modification, firm regional variant, or special internal application routing firmware profile (overrides the standard “N” final digit designation for specific switchgear configurations)
Product Introduction
The ABB REF610C11HCR01 is a specialized numerical feeder protection relay designed to implement non-directional overcurrent and earth-fault protection schemes in medium-voltage distribution sub-stations, industrial grids, and power generation loops. This precise variant features a high-voltage universal power supply ($110\text{–}240\text{ VAC/VDC}$), making it perfectly suited for standard plant layouts energized by centralized DC battery banks. It acts as an independent Intelligent Electronic Device (IED) to protect transformers, motors, and radial distribution cables from high-current thermal overloads and phase short-circuits.
Engineered with a modular draw-out physical frame, the internal active processor tray can be quickly unlatched and pulled from its matching case sleeve without disturbing any hard-wired field terminal connections at the rear of the panel. The processing engine performs true RMS calculations on multi-phase currents, ensuring robust immunity against nuisance tripping caused by high-order transient harmonics or transformer inrush profiles. Additionally, the unique “R01” suffix ensures compatibility with specific customized software parameters or specific regional engineering standards, allowing the relay to serve as a reliable drop-in replacement asset for matched switchgear protection lines.
