Lennox 54G52 Transformer

The Lennox 54G52 Transformer is a critical OEM replacement part engineered for high-demand commercial and industrial HVAC applications. This step-down transformer features a 460V primary voltage and a 230V secondary voltage, delivering a robust 115VA power rating to maintain stable control circuit voltage for your equipment. Designed to meet strict Basler Systems specifications, the 54G52 (also identified as part number 54G5201) ensures seamless integration with Lennox LGA and GCS series rooftop units and air handlers.

For technicians servicing high-voltage systems, this unit provides the necessary electrical voltage conversion to power essential components such as contactors, relays, and control boards without current fluctuation. Its heavy-duty construction is built to withstand the thermal stress and vibrational demands of mechanical rooms. Whether you are performing a preventative maintenance swap or a critical field repair, the Lennox 54G52 delivers the precise secondary output required for peak system performance.

• Precise Voltage Regulation: Converts 460VAC to 230VAC at 60Hz, protecting sensitive electronics from overvoltage.
• High Load Capacity: Rated at 115VA, providing ample power for complex control strings and multiple contactors.
• OEM Compatibility: Direct replacement for Lennox part numbers 54G5201 and BE22339001, ensuring exact physical and electrical fitting.
• Industrial-Grade Build: Designed for longevity in high-ambient temperature environments common in commercial HVAC systems.

What models are compatible with the Lennox 54G52?
This transformer is widely used in Lennox LGA120, LGA240, and GCS16X series units. It is compatible with any system requiring a 460V to 230V step-down with a load under 115VA.

Can I use this to replace a 50VA or 75VA transformer?
Yes, as long as the primary and secondary voltages match. Increasing the VA rating to 115VA provides additional overhead and can prevent overheating in circuits that were near the limit of a lower-rated transformer.

Does this unit include internal fusing?
Always verify the specific wiring diagram for your Lennox unit; while some Basler-style transformers have integrated protection, we recommend checking the HVAC control circuit for existing inline fuses during installation.
