White Rodgers 90-T40M1 Transformer 40VA

The White Rodgers 90-T40M1 is a 40 VA transformer that steps 120 V primary voltage down to 24 V secondary at 60 Hz. Its multi-mount design lets HVAC technicians secure it in several orientations during furnace or air-handler installations.

Multi-mount flexibility simplifies wiring

The multi-mount feature removes the need for a single fixed bracket, so installers can choose the clearest wiring path in tight cabinets. Buyers who need a higher VA rating or a different primary voltage will have to select another model.

Highlights

  • Delivers 40 VA for reliable low-voltage control
  • 120 V primary suits standard mains supply

Questions about this item

Does the 40VA transformer require any scheduled maintenance or internal part replacement?

The sealed 40VA unit has no user-serviceable parts; if the windings or insulation fail the whole transformer is replaced.

What limit appears first when the 40VA 24V secondary runs continuously at full load?

The 40VA rating is the thermal ceiling; sustained draw at that level will hit the temperature limit before any voltage drop occurs.
