Product Details
The ABB REJ603BBB10NN3XC, also cataloged as the REJ603 Self-Powered Feeder Protection Relay, operates as a dedicated hardware component for phase overcurrent, earth fault, and voltage monitoring tasks within Relion 600 secondary distribution platforms. Configured to function via direct loop power harvested from the main current transformers, the device triggers mechanical trip coils through dedicated binary output lines when electrical thresholds are exceeded.

Backplane Bus Communication Velocity Licences Profile
The integration of this self-powered element into broader industrial arrangements requires matching specific hardware profiles to prevent bus degradation. Gating logic and trip execution are processed on local registers that maintain stable states regardless of backplane bus communication velocity licences constraints. The internal layout maps I/O density scaling options through manual DIP switches, ensuring absolute firmware flash compatibility with localized transformer safety interlocks and reducing hardware processing latency during severe phase faults.
Frequently Asked Questions
Q: What are the live removal restrictions for the REJ603BBB10NN3XC module?
A: Hot-swapping or unlatching the terminal block while the primary feeder is live is prohibited. Current transformer secondary connections must be short-circuited externally prior to physical decoupling to eliminate high inductive voltage generation.
Q: How does the device maintain configuration settings when the feeder line drops power?
A: Thresholds established via the hardware DIP switch matrix or saved to the non-volatile internal data storage remain preserved during line blackouts, requiring no active battery back-up path.
Q: What is the limitation regarding the startup power requirement?
A: The internal processing circuits require at least 2.5 VA of energy from the CT secondary line to initialize the protection routines and execute a valid binary trip command.
Field Installation Guidelines
- Current Transformer Terminals Pre-Check: Verify that all connection poles are tightly engaged and paired with matching 1 A or 5 A selectable terminals. Do not leave CT circuit runs loose during initial commissioning phases.
- Low-Voltage Signal Separation: Route the binary I/O signal lines separate from adjacent heavy AC phase bars. Keep terminal cable paths isolated inside designated, grounded wireways.
- Enclosure Earthing Continuity: Connect a low-impedance ground conductor from the rear IP20 frame screw directly to the copper master ground rail of the distribution cubicle.
