The ABB REF630 (Part Number: 1KHL160003R0001) represents a pinnacle in the Relion® 630 series, specifically designed for feeder protection and control in utility and industrial power systems. This multifunctional relay manages radial, looped, and meshed networks with precision. It integrates protection, control, measurement, and supervision into a single rack-mounted unit, facilitating the transition toward smart grid modernization. We supply this unit as 100% Brand New and Original with spot goods availability for expedited deployment.

Grid Topology Versatility: The REF630 supports diverse network structures. Whether your facility operates on a simple radial feeder or a complex meshed grid with distributed generation, this relay adapts its logic to ensure selective fault isolation.
Seamless Substation Automation: By natively supporting IEC 61850, the module enables horizontal GOOSE communication between IEDs. This eliminates extensive hardwiring, reduces installation costs, and accelerates system response times during critical fault events.
Integrated Breaker Management: Beyond protection, the unit controls circuit breaker operations, including interlocking and multi-shot autoreclosing. This consolidation reduces the number of components required in the switchgear panel.
Advanced Disturbance Recording: The internal memory captures high-resolution event logs and disturbance data. Engineers use this data to perform post-fault analysis, identifying the root cause of grid instabilities without requiring external monitoring hardware.
Universal Power Compatibility: The wide-range power supply (100–240 V AC or 48–250 V DC) simplifies inventory management. A single part number covers almost all substation auxiliary power standards.
Is the 1KHL160003R0001 model suitable for distributed generation (DG) integration?
Yes. The Relion 630 series includes specific algorithms to handle the bidirectional current flows and protection challenges associated with connecting solar, wind, or small-scale hydro to the distribution grid.
Can I replace an older REF series relay with this REF630 unit?
The REF630 offers backward compatibility in terms of protection philosophy, but you must verify the physical dimensions and terminal mapping. The 630 series typically provides higher I/O density and superior communication protocols compared to legacy REF541 or REF543 models.
How does the unit handle high-temperature environments?
While rated for up to +55°C, performance in high-ambient areas (like unventilated outdoor kiosks) requires attention to airflow. The relay includes internal self-diagnostics that monitor thermal health and trigger alarms before hardware failure occurs.
Does this relay support PROFIBUS or only IEC 61850?
The 1KHL160003R0001 primarily focuses on IEC 61850, Modbus, and DNP3. For PROFIBUS integration, we recommend verifying if an additional communication gateway or specific optional module is required for your site architecture.
