Bard part 8407-049 is an OEM stepdown transformer rated 3 kVA, designed to convert a 400V supply to 220V where Bard commercial wall-mount HVAC equipment is configured to run controls or accessories at the correct line voltage. When a unit is installed in facilities with higher incoming power, this transformer helps protect downstream components by providing the proper voltage and stable electrical isolation. Use Bard 8407-049 when replacing a failed transformer or restoring factory electrical performance, and confirm primary and secondary voltage requirements and mounting space against your unit wiring diagram before ordering.
* Orders less than $50 may incure a minimum order fee.
