ABB REF610C11HCNN01
Product Introduction
The ABB REF610C11HCNN01 is a versatile feeder protection relay designed for industrial power distribution networks up to 15 kV. As part of ABB’s Relion® 610 series, this integrated electronic device (IED) provides comprehensive protection, control, and monitoring for medium-voltage switchgear. The package includes the ABB SAQH1 hot-swappable base, enabling rapid module replacement without wiring disconnection.
Engineered for reliability in harsh environments, the ABB REF610C11HCNN01 combines advanced protection algorithms with arc-flash detection capability. Its dual-core processor executes 12-cycle waveform analysis for fault discrimination, while the integrated energy meter tracks consumption for load management. The relay serves as a critical node in ABB’s System 800xA, enabling centralized fault analysis and predictive maintenance through IEC 61850 GOOSE messaging.
Core Advantages and Technical Highlights

Self-supervision alerts on component degradation
Typical Application Scenarios
Industrial Plant Switchgear: Protects 6.6kV feeders for critical motors in petrochemical facilities. Arc-flash detection reduces incident energy by 90% via ABB REF610C11HCNN01‘s <2ms light sensing.
Renewable Energy Substations: Manages 33kV collector feeders in solar farms. Voltage-dependent overcurrent settings prevent nuisance tripping during cloud transients.
Marine Power Distribution: DNV-GL certified for vessel switchboards. Ground fault protection (50N) with directional logic isolates faults without blackout.
Mining Power Networks: Withstands 5g vibration in crusher motor circuits. CB failure protection (50BF) initiates backup tripping when dust affects main breaker.
Data Center MV Distribution: Monitors 12kV UPS input feeders. IEC 61850 enables real-time load shedding coordination with ABB PCS6000 converters.
