ABB REF615C_C HCFFAEAGANB2BAN1XC
Product Introduction
The ABB REF615C_C HCFFAEAGANB2BAN1XC is an advanced feeder protection relay engineered for medium-voltage switchgear (up to 15 kV), integrating arc flash detection and comprehensive protection in a compact platform. This specific variant features hardware-accelerated ARC (Arc Protection) functionality with native light/pressure sensor inputs, reducing fault clearance time to <4 ms – critical for personnel safety. The relay executes 12 protection functions concurrently, including directional overcurrent (67) and sensitive earth fault (50N/51N), while supporting IEC 61850 Ed.2.1 process bus architecture.
Designed for harsh environments, its “-40°C” rating and ATEX compliance enable deployment in LNG terminals and mining substations. The REF615C_C variant includes enhanced transient recording (128 cycles) for detailed fault analysis and conformal-coated PCBs for humidity resistance. As part of ABB’s Relion® 615 series, it seamlessly integrates with ABB’s UFC921A101 OPC UA gateways for enterprise data exchange.
Core Advantages and Technical Highlights
Ultra-Fast Arc Mitigation: Integrated optical (3 channels) + pressure (1 channel) sensor inputs trigger trip signals in 2-4 ms – 3× faster than external systems. Patented light-intensity discrimination ignores welding flashes.
Cybersecurity Hardening: Hardware-enforced secure boot chain with TPM 2.0. Configuration changes require physical keys + biometric authentication. Audit trails meet NERC CIP-014.
Dynamic Grid Adaptation:
Auto-calibration for CT saturation (detects >15% error)
Adaptive cold load pickup logic prevents nuisance tripping
Synchrophasor measurement (IEEE C37.118.1) for grid instability detection
Unified Diagnostics:
Real-time contact erosion monitoring (% wear calculation)
Insulation resistance trending (predicts cable degradation)
Arc sensor self-test with optical path verification
Seamless Integration:
Plug-and-play with ABB’s 3BHE039203R0101 I/O modules
Pre-mapped GOOSE signals for breaker failure schemes
Typical Application Scenarios
Offshore Wind Substations:
Detects arc faults in salt-fog-exposed switchgear
Directional overcurrent (67N) prevents false trips during cable switching transients
IEC 61850 GOOSE coordinates with turbine protection
Steel Mill MCCs:
Monitors 6kV motor feeders with 46 negative-sequence protection
Pressure sensors detect arc blasts behind closed panels
Survives 50g shock during slab handling
Data Center Power Chains:
81H/81L frequency protection maintains UPS synchronization
Light sensors installed in busway joints
Cyber-hardened configuration blocks unauthorized access
