Bard 8407-050BX - 480V to 24V 75VA Transformer
Bard part number 8407-050BX is an OEM boxed control transformer that steps 480 VAC primary power down to 24 VAC at 75 VA to supply the low voltage used by thermostats and internal control circuits in Bard wall mounted HVAC equipment. A properly sized transformer helps keep relays and boards operating reliably, and it is a common replacement when a unit has no 24 volt control power or shows intermittent control issues. Confirm your unit voltage and match the 480 to 24 VAC rating and VA capacity before ordering, and verify terminal placement and mounting in your Bard wiring diagram for a quick, correct swap.

What does the "BX" suffix mean?
Bard uses suffixes like "BX" to manage parts internally. These do not change the physical form or function of the part.
A part number ending in "BX" simply means it is packaged in a box for shipping, rather than for internal assembly use.
Example: 8406-142BX is physically identical to 8406-142.
