Bard 8407-045BX - 120V to 24V 40VA Transformer
The Bard 8407-045BX is an OEM 120V to 24V, 40VA control transformer used in Bard wall mount and related HVAC equipment to supply steady 24 volt power for the low voltage control circuit, including contactors, relays, and other control components. If your unit is blowing low voltage fuses, losing thermostat control power, or showing intermittent control operation, replacing the transformer is a common corrective step, provided wiring and downstream shorts have been ruled out. This boxed Bard factory replacement is intended to match original electrical ratings and mounting fit so you can restore proper control voltage and dependable system operation with an exact Bard part.

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.
