Carrier HT01CN241 Transformer

The Carrier HT01CN241 Transformer is a Factory Authorized Parts replacement specifically engineered to maintain the electrical integrity of Carrier, Bryant, and Payne HVAC systems. This single-phase step-down transformer converts 208/230V primary voltage to a stable 24V secondary output, providing the necessary 40VA power rating for control boards, contactors, and thermostats. As the direct updated version for HT01BD208, it ensures seamless compatibility without the need for field modifications or bracket adjustments. The heavy-duty construction is designed for 50/60 Hz cycles, making it a versatile OEM HVAC control transformer for both residential and light commercial air handlers and furnaces. For technicians troubleshooting low-voltage circuits, the HT01CN241 features integrated 3/16-inch and 1/4-inch quick-connect terminals to streamline installation and ensure secure electrical junctions under high-vibration conditions.

Common Technical Questions

What is the maximum load this transformer can handle?
The Carrier HT01CN241 is rated at 40VA. To prevent over-current issues or core saturation, ensure the total volt-ampere draw of your 24V components—such as contactor coils and thermostats—does not exceed this rating.

Can I use this to replace a transformer with a lower VA rating?
Yes, a 40VA transformer can typically replace a 20VA or 30VA unit, provided the voltage specs match, as the system will only draw the amperage it requires. However, you cannot replace a higher VA unit with this model.

Is this compatible with 120V primary systems?
No, this specific model is designed for 208/230V primary voltage. Using this on a 120V circuit will result in insufficient secondary voltage and failure of the control system.
