UL 3573 ignition lead wire for gas appliance internal ignition wiring
Product Overview
UL 3573 ignition lead wire is often reviewed for gas appliance internal ignition wiring where the lead serves a defined role inside the appliance ignition system. In these products, the wire is usually enclosed and protected, but its job is more specialized than ordinary internal appliance wiring. That is why buyers select it according to its actual use inside the ignition path rather than by general wire category alone.
This makes UL3573 a practical choice for OEM gas appliances where internal ignition lead routing needs a wire better aligned with the function of the product.

Key Ratings
- UL Style: UL 3573 (AWM, UL 758)
- High temperature ignition lead wire construction
- Application type: gas appliance ignition wiring
- Conductor: stranded copper, tinned copper optional
- Internal use: protected ignition-related internal routing

Why Buyers Use It in Gas Appliances
Gas appliances often include ignition-related lead sections that are more specialized than the rest of the product wiring. Buyers choose UL3573 when they want a lead wire that fits this protected internal ignition role better than standard internal wire would.
This is especially important in products where the ignition lead operates within a specific equipment layout and needs a construction that suits long-term appliance use.

Typical Applications
- Gas appliance ignition leads
- Internal ignition routing in gas-fired equipment
- OEM gas appliance assemblies
- Protected lead paths in appliance ignition systems
- Specialized internal ignition-related wiring

Procurement Notes
When requesting quotation, buyers usually confirm conductor size, insulation color, package format, and the exact appliance application. It is also useful to clarify whether the lead is part of a gas ignitor, burner module, or another protected ignition-related section.
Selection Notes
If the application is more directly aligned with gas ignitor system wire, UL3304 may also be compared. If the project needs a broader high voltage silicone wire, UL3239 may be relevant. UL3573 is more suitable where the internal lead belongs to a gas appliance ignition system and product-specific fit matters.
