Rheem-Ruud 46-22863-82 Fuses

The Rheem-Ruud 46-22863-82 Fuses are essential HVAC control circuit fuses designed to provide supplemental overcurrent protection for sensitive electronic components. This OEM 5-pack 2amp GlassFastAct selection features a fast-acting glass cartridge design, specifically engineered to interrupt electrical faults and short circuits before they can damage transformers or integrated furnace control (IFC) boards. With a maximum voltage rating of 350V AC and an interrupting capacity of 100A, these 2-amp fuses are standardized for consistent performance in light-duty applications where a time-delay fuse would be too slow to react.

For technicians servicing Rheem, Ruud, or Weather King equipment, these fuses are listed for use in various gas furnace platforms, including the 80PJ, 90TJ, RGDG, and RGPH series. Measuring 15mm (0.577 inches) in length and 4.5mm (0.177 inches) in diameter, they serve as a direct Littelfuse 2AG-229-002 cross-reference. Maintaining a stock of these 2A glass fuses in your service truck ensures you can quickly restore 24V control power and avoid unnecessary return trips on critical no-heat calls.

• Instant Fault Interruption: The fast-blow glass fuse response prevents low-voltage surges from damaging expensive furnace control boards.
• Precise OEM Fitment: Designed specifically for HVAC supplemental protection, matching the 4.5mm x 15mm cartridge footprint of original factory installations.
• High Voltage Compatibility: Rated for up to 350V AC, making them suitable for 24V, 120V, and 240V internal circuit protection.
• Multi-Pack Value: The 5-pack configuration provides professional contractors with reliable spares for multiple service calls.

• Can I use a 3-amp fuse if I run out of 2-amp fuses? No. Over-fusing a circuit risks permanent damage to the primary control board or transformer. Always use the specified 2-amp rating.
• Is a slow-blow fuse a suitable substitute for the 46-22863-82? No. Fast-acting fuses are required for sensitive electronics to ensure the circuit opens immediately during a short.
• How do I verify if the fuse is blown? While visual inspection of the internal element is a quick check, use a multimeter to test for continuity across the end caps to be certain.
