Description
Model Suffix Decoder
The multi-character configuration identifier HBFFAFAGNCA1BNA11G breaks down into the following physical and functional factory build parameters:
- H: Platform hardware revision level designation (Relion 615 Series baseline generation)
- B: Baseline operational region / application standard (IEC design suite compliant)
- F: Dedicated feeder protection application firmware library block
- F: Standard Configuration F hardware and application template (pre-mapped functional routing typically focusing on specialized feeder applications such as directional protection and extended I/O)
- A: Conventional $1\text{ A} / 5\text{ A}$ analog current transformer (CT) input card
- F: Conventional analog voltage transformer (VT) input card profile matching Configuration F specifications
- A: Standard binary I/O allocation layout configuration (defines primary discrete input and output relay count)
- G: Specific communication board hardware configuration (Ethernet network interface layout)
- N: Uncoded/Standard internal hardware variance step allocation
- A: Default internal standard component packaging material configuration
- A: Primary language group template configuration option (English standard menus)
- 1: Standard serial or Ethernet system communication architecture configuration variant level 1
- B: High-resolution multi-line graphical LCD operator interface screen (supports real-time customizable single-line diagrams and localized mimics)
- C: High-voltage universal power supply engine block ($100\text{–}240\text{ V AC / } 48\text{–}250\text{ V DC}$ nominal operational coverage)
- N: Default system tracking factor configuration
- 1: Factory processing code iteration level
- 1: Standard serial or Ethernet system communication architecture configuration variant level 1
- G: Final tracking factory assembly, environmental conformance, and revision version block tag
Product Introduction
The ABB REF615 HBFFAFAGNCA1BNA11G is a numerical feeder protection and control terminal belonging to the globally recognized Relion 615 product family. Housed in a compact withdrawable enclosure, this unit is specifically built around Standard Configuration F. This profile integrates traditional three-phase overcurrent mechanisms with directional earth-fault protections ($I_0$), directional phase-angle monitoring, and complete network voltage/frequency supervision matrix blocks. It acts as an Intelligent Electronic Device (IED) that serves as the primary automation and safety gateway for utility distribution substations, plant main incoming breakers, and segmented radial or looped network designs.
