Description
The Lennox 17G86 is an OEM replacement reactor (line choke) engineered specifically for use with Lennox 4kW Gen2 inverter-driven HVAC systems. Reactors play a critical role in variable-frequency drive and inverter circuits by smoothing current waveforms, suppressing voltage spikes, and reducing total harmonic distortion (THD) — all of which extend the service life of the inverter and connected components.
Key Features
- OEM Lennox replacement part — ensures precise fit and compatibility with Gen2 inverter platforms
- Rated for 4kW inverter applications
- Reduces harmonic distortion in inverter output circuits
- Limits inrush current to protect sensitive inverter electronics
- Suppresses voltage transients and line-side interference
- Supports stable, efficient inverter operation and extended component life
- Genuine Lennox quality construction for reliable, long-term performance
Application
Designed as a direct OEM replacement for Lennox Gen2 inverter-equipped systems requiring a 4kW reactor. Always verify compatibility with your specific Lennox equipment model before installation.
