Transformer SFTRR40VA – Genuine OEM Replacement Multi-Tap 40VA Control Transformer

The SFTRR40VA is a versatile, high-capacity genuine OEM step-down transformer designed to power the low-voltage control circuits in a wide range of Trane and American Standard HVAC systems. This component is the electrical "heart" of your unit, converting high-voltage incoming power into the 24V required to operate thermostats, contactors, relays, and integrated furnace or air handler control boards.

Technically engineered for flexibility, the SFTRR40VA features multi-tap primary leads, allowing it to be used in residential (120V) or commercial (208/240V) applications. With an upgraded 40VA rating, it offers more "headroom" than standard 35VA models, ensuring stable power delivery even in systems with multiple accessories like humidifiers or electronic air cleaners. Its heavy-duty construction is designed to withstand the heat and vibration common within an HVAC cabinet, providing years of silent, hum-free operation.

Key Features and Function:

  • Multi-Tap Input: Supports 120V, 208V, and 240V primary connections for maximum field versatility.

  • 24V Secondary Output: Provides the industry-standard low voltage for all modern HVAC safety and control components.

  • High 40VA Capacity: Delivers increased power output to prevent control board "brownouts" during high-demand cycles.

  • Universal Foot Mount: Features a standard mounting bracket that aligns with most factory screw patterns for a quick swap.

  • Manufacturer: Trane / American Standard (Genuine OEM)

  • Part Type: Multi-Voltage Control Transformer

  • Primary Voltage: 120 / 208 / 240 VAC

  • Secondary Voltage: 24 VAC

  • Capacity: 40VA

  • Frequency: 50 / 60 Hz

  • Shipping Weight: 2.4 lbs

🛠️ HVAC Depot Pro Tip: Wire Management is Key

When installing the SFTRR40VA, you will have multiple primary "tap" wires (usually White, Black, Red, and Orange). Only connect the wires that match your incoming voltage and securely cap off the unused leads with wire nuts. Leaving an unused high-voltage lead exposed inside the cabinet can cause a dangerous short circuit to the ground, potentially destroying your new transformer or the main control board.

Cross-Reference & Compatibility:

The SFTRR40VA is a direct OEM replacement for the following part numbers:

  • OEM Numbers: TRR00187, TRR00150, TRR01250, TRR02193

  • Aftermarket: Packard TF40, Mars 50203, Jard 4031F

Extensive Model Compatibility List:

  • Trane Air Handlers: TWE, TEE, and GAM series units.

  • Trane Heat Pumps & ACs: 2TTA, 2TWA, 4TTA, 4TWA series condensers.

  • American Standard Heritage & Allegiance: Various residential split-system units.
