Why this matters in your panel

The SB461RG isn’t just a fuse holder—it's a protective module that integrates seamlessly with GE Spectra gear to deliver fast, predictable interruption during fault events. By housing the right fusing for your feeders, it helps minimize arc flash exposure, protects downstream equipment, and simplifies maintenance with straightforward fuse replacement. Its 30A rating and 480/600V capability align with many mid- to high-voltage distribution setups found in manufacturing, data centers, and facilities with demanding power needs.

Ideal applications

• Industrial facilities and manufacturing lines using 480V or 600V three-phase power
• Electrical switchgear retrofits requiring reliable, fuse-protected protection for feeders
• Data centers or commercial complexes that rely on modular Spectra Series protection strategies

How it integrates with your system

Designed for compatibility within the GE Spectra ecosystem, the SB461RG plugs into the bus-bar assembly to provide immediate, discrete overcurrent protection for each phase. Its fusible design supports fast isolation of faulted circuits, helping you maintain uptime and system reliability without extensive rework.

Practical usage tips

• Verify your distribution panel is a compatible Spectra Series model and that the SB461RG matches the bus-bar configuration
• Pair with the correct fuse type and rating for your specific load profile to avoid nuisance tripping
• Schedule periodic inspections of fusible components and connections to ensure solid contact and corrosion-free operation
