ABB REF620 Feeder Protection Relay - NBFNAANNNBA1BNN11G

The ABB REF620 is an advanced feeder protection and control relay engineered for comprehensive protection of medium voltage distribution networks, overhead lines, and cable feeders. Model NBFNAANNNBA1BNN11G delivers multi-functional protection capabilities with integrated control, measurement, and communication features designed for modern substation automation systems.

Technical Specifications

  • Protection Functions: Overcurrent (ANSI 50/51), Earth fault (50N/51N), Directional overcurrent (67/67N), Voltage protection (27/59), Frequency protection (81), Circuit breaker failure (50BF)
  • Communication Protocols: IEC 61850, Modbus, DNP3, IEC 60870-5-103
  • Rated Voltage: 100-240V AC/DC auxiliary power supply
  • Current Inputs: 1A or 5A nominal, thermal withstand 4x In continuous
  • Binary Inputs: Configurable for status monitoring and interlocking
  • Output Relays: High-speed trip contacts with programmable logic
  • Display: Graphical LCD with local HMI for configuration and diagnostics
  • Operating Temperature: -40°C to +70°C (-40°F to +158°F)

Application Scenarios

The REF620 excels in utility substations, industrial power distribution systems, renewable energy installations, and critical infrastructure protection. Its arc flash detection capability enhances personnel safety by enabling rapid fault isolation. The relay integrates seamlessly into SCADA systems via multiple communication protocols, supporting centralized monitoring and control architectures.

Advanced Protection Solutions

Equipped with adaptive protection algorithms, the REF620 automatically adjusts settings based on network topology changes and operational modes. The built-in disturbance recorder captures fault events with high-resolution waveform data for post-event analysis. Self-supervision diagnostics continuously monitor relay health and communication status, ensuring maximum system reliability.

Integration & Compatibility

Native IEC 61850 support enables plug-and-play integration with modern substation automation platforms. The relay's flexible I/O configuration accommodates diverse application requirements, from simple feeder protection to complex interlocking schemes. Cybersecurity features including role-based access control and encrypted communication protect against unauthorized access.
