8407-037 OBSOLETE
- Transformer 480/24V 55VA
The Bard 8407-037 transformer is an OEM control transformer used in Bard wall mounted HVAC equipment to step down 480VAC line power to a stable 24VAC control voltage, rated at 55VA for reliable operation of contactors, relays, and other low voltage control circuits. Replacing a weak or failed transformer with the correct Bard part helps prevent nuisance shutdowns, control power drops, and intermittent calls that can look like board or thermostat issues. Verify your unit voltage and compare the VA rating and wiring terminals to your original transformer before ordering so it matches your factory control circuit requirements.
