Product Overview: GE F650BFBF1G0HI Feeder Management Relay
1. General Description
The GE F650BFBF1G0HI is a advanced Digital Feeder Management Relay from the renowned GE Multilin F650 series. It is designed as a comprehensive, all-in-one solution for the protection, control, automation, and monitoring of electrical distribution assets, primarily feeders and overhead lines, in utility, industrial, and commercial power systems.
This relay integrates multiple protection functions, advanced automation logic, high-resolution metering, and robust communication capabilities into a single, compact device. Its primary purpose is to enhance system reliability by quickly isolating faults, preventing equipment damage, and providing valuable data for operational decision-making.
2. Key Features and Functions
- Comprehensive Protection Suite: Includes a wide array of protection functions, such as:
- Overcurrent Protection (50/51, 50HS/51HS): Phase and ground time and instantaneous overcurrent protection, with high-set elements for fast fault clearing.
- Directional Overcurrent (67/67N): Critical for selective coordination in networked systems like ring mains or parallel feeders.
- Earth Fault Protection (50G/51G, 50N/51N): Sensitive ground fault detection using residual current.
- Negative Sequence / Unbalance (46): Protects equipment from thermal damage due to phase unbalance.
- Thermal Overload (49): Provides thermal protection for cables based on current measurement.
- Automatic Reclosing (79): Configurable for multiple reclosing shots to restore service after temporary faults, essential for overhead lines.
- Under/Over Voltage (27/59) and Under/Over Frequency (81O/81U): Protects against abnormal system voltage and frequency conditions.
- Control & Automation:
- Programmable Logic (FlexLogic™): Powerful integrated logic allows users to create custom control schemes, interlocking, and automation sequences without additional hardware.
- Multiple Control Elements: Includes virtual switches, latches, timers, and counters.
- Monitoring & Metering:
- High-Accuracy Measurements: Real-time values for currents, voltages, frequency, power (kW, kvar, kVA, PF), energy, and demand.
- Disturbance Recorder: High-resolution oscillography for detailed post-fault analysis.
- Sequence of Events (SOE) Recorder: Time-stamped log of all operations and changes with millisecond accuracy for diagnostics.
F650-B-F-G-F-1-G-1-HI-E
- Communication & Integration:
- Multiple Protocol Support: Native support for IEC 61850, DNP3 LAN/WAN, Modbus RTU, and IEC 60870-5-103/104.
- Redundant Ethernet Ports: Dual Ethernet ports for high-availability communication networks.
- Integrated HMI: Large, backlit graphical LCD display and keypad for local interface and configuration.
3. Technical Specifications
| Parameter | Specification / Description |
|---|---|
| Product Line | GE Multilin F650 Feeder Management Relay |
| Auxiliary Supply (Vs) | The suffix 1G indicates a wide-range 125-250 V DC / 100-240 V AC power supply. |
| Rated Current (In) | The suffix 0H typically indicates a 1 A rated current input. (A common alternative is 0Lfor 5A). |

4. Ordering Code Breakdown: F650BFBF1G0HI
The part number is structured to define the hardware configuration:
- F650: Base product model.
- B: Communication Option 1: Dual Ethernet ports (front).
- F: Communication Option 2: Fiber optic port (rear).
- B: Communication Option 3: RS485 port (rear).
- F: Communication Option 4: DNP3 LAN/WAN protocol license.
- 1G: Auxiliary Power Supply: 125-250 V DC / 100-240 V AC. This is the key difference from the
2Gvariant (24-48V). - 0H: CT Rating: 1 A.
- I: Voltage Rating: 120/240 V AC (for the sensing VT circuit).
5. Typical Applications
The F650 is deployed in a wide range of medium-voltage applications:
- Utility Distribution Feeders (incoming and outgoing)
- Industrial Plant Main Feeders
- Ring Main Units (RMUs)
- Overhead Line Protection and Auto-Reclosing
- Backup Protection for Transformers
- Substation Automation systems compliant with IEC 61850.
6. Important Note
- The F650 is a highly configurable device. The specific functionality available (e.g., Directional Overcurrent, Auto-Reclosing) is enabled via software licenses that must be purchased and activated separately from the hardware.
- Configuration and setting management are performed using GE’s Enervista UR Setup software.
- Key Difference from F650BFBF2G0HIE: The primary difference between this model (
1G) and the one in the previous query (2G) is the auxiliary power supply. The1Gmodel supports a higher voltage range (100-240V AC/125-250V DC), making it suitable for standard station DC battery supplies and AC control power, while the2G(24-48V) is for lower voltage systems. The missingEsuffix indicates a different language or minor revision variant. - For absolute precision, always refer to the official GE F650 Instruction Manual and the specific drawing for this order code.
