Bard 8407-051 - Control transformer
Bard part number 8407-051 is an OEM control transformer used in select Bard wall mounted HVAC equipment to step down higher line voltage to a 230 volt control supply for proper operation of relays, contactors, and other internal controls. This transformer is specified for multi voltage primary power inputs, including 277V, 460V, and 575V, making it a common fit where the same unit platform is applied across different building power services. Replacing a weak or failed transformer with the correct Bard OEM part helps restore stable control voltage, reduces nuisance shutdowns, and protects downstream electrical components. Always confirm unit model and wiring diagram to verify primary tap selection and secondary voltage requirements before installation.
