Fenwal 05-125948-148 Cable

The Fenwal 05-125948-148 is a professional-grade high voltage ignition cable specifically engineered for reliable spark delivery in gas-fired burner systems. This 5mm diameter cable features .25 inch female quick connect terminals on both ends, ensuring a secure, low-resistance interface between the direct spark ignition (DSI) control and the electrode assembly. Designed to handle the 15kV to 25kV surging energy required for consistent ignition, this cable utilizes high-temp insulation to maintain dielectric strength in demanding HVACR environments. With a 48-inch length, it provides the necessary reach for standard furnace ignition systems and commercial boiler configurations. As a critical OEM replacement part, it is built to UL and CSA standards, providing technicians with a precise fit that eliminates the risks associated with field-modified universal leads. Total system performance depends on the integrity of the spark circuit, making this factory-terminated Fenwal ignition lead the standard choice for maintaining flame rectification and preventing nuisance lockouts.

• Optimized Conductivity: Features factory-crimped .25" female QC terminals for maximum energy transfer and reduced EMI noise.
• High-Temperature Durability: The 5mm insulated jacket is rated for extreme thermal environments common in compact heat exchangers.
• Application Versatility: Direct compatibility with Fenwal 35 Series ignition modules and various gas-fired appliances.
• Reliable Spark Execution: Engineered to withstand high voltage discharge without insulation breakdown or voltage leak.

What is the maximum voltage rating for the Fenwal 05-125948-148?
This cable is designed to safely transport the 15,000 to 25,000 volts generated by standard gas ignition controls to the electrode.

Can this cable be used for flame sensing?
Yes, this high voltage lead is suitable for both spark ignition and remote flame sensing applications using the flame rectification principle.

Is the length adjustable in the field?
It is recommended to use the factory-terminated 48-inch length to ensure terminal integrity; however, always consult the appliance manual for specific HVAC ignition cable routing requirements.
