• TRANSFORMER 40VA 240/24V

Bard 8407-020 is an OEM 40VA control transformer designed to step down a 240V primary supply to 24V for the low-voltage control circuit in compatible Bard wall-mount HVAC equipment. A properly sized transformer is critical for stable operation of the thermostat circuit, contactor coils, relays, and control boards, and this part is built to Bard specifications for correct fit and dependable 24V output under load. Confirm the unit model and wiring diagram before ordering, and match the primary voltage and VA rating to the original transformer to avoid nuisance fuse trips or low-voltage drop issues.
