ABB REF615A_E HAFAABAAABE1BCA1XE
Product Introduction
The ABB REF615A_E HAFAABAAABE1BCA1XE is an advanced feeder protection relay from ABB’s Relion® 615 series, designed for medium-voltage applications in industrial and utility power systems. This specific variant (HAFAABAAABE1BCA1XE) represents a fully-featured configuration with arc flash protection and enhanced communication capabilities.
As part of ABB’s digital substation solutions, the REF615A_E provides comprehensive protection for overhead lines, underground cables, and busbars up to 40.5kV. The relay combines traditional overcurrent and earth fault protection with innovative arc flash detection technology, offering both equipment protection and personnel safety. Its modular design allows flexible adaptation to various network configurations and protection requirements.
Core Advantages and Technical Highlights
Advanced protection scheme: The ABB REF615A_E HAFAABAAABE1BCA1XE features directional/non-directional overcurrent protection (50/51, 50N/51N) with multiple characteristic curves. The integrated arc flash protection uses light detection to trigger ultra-fast tripping (<7ms), significantly reducing incident energy in fault conditions.
Communication capabilities: This variant supports IEC 61850 Edition 2 communication standard including GOOSE messaging for fast peer-to-peer communication. Additional protocols (Modbus RTU/TCP, DNP3.0) ensure compatibility with various SCADA and control systems. The rear communication interface includes 2x Ethernet ports and 1x RS485 port.
User-friendly operation: The relay features a high-resolution graphical LCD with intuitive menu navigation. The front panel includes 10 programmable LEDs, 5 pushbuttons, and a navigation wheel for local control. The REF615A_E supports ABB’s PCM600 and Asset Vision tools for advanced configuration and condition monitoring.
Robust construction: Designed for demanding environments, the relay withstands severe electromagnetic interference (4kV surge immunity) and mechanical vibrations. The compact design allows space-efficient panel mounting while maintaining excellent heat dissipation.
Typical Application Scenarios
The ABB REF615A_E HAFAABAAABE1BCA1XE is particularly valuable in industrial plants requiring enhanced safety and protection. In oil refineries and chemical plants, its arc flash protection significantly reduces risks associated with electrical faults in hazardous areas. The relay’s sensitive earth fault detection (50N/51N) ensures reliable operation in resistance-grounded networks common in industrial facilities.
For utility applications, this protection relay is deployed in distribution substations protecting feeders in complex network configurations. Its directional overcurrent capability makes it suitable for ring main systems with bidirectional power flow. Renewable energy installations benefit from its adaptive protection settings that accommodate generation fluctuations in solar parks and wind farms.
