Bard 8407-041BX - 24V Control Transformer
The Bard 8407-041BX is an OEM control transformer used in Bard HVAC equipment to step incoming line voltage down to 24 volts for the low voltage control circuit that powers and protects components like relays, contactors, and control boards. This transformer supports multiple primary voltages (120, 208, or 240 VAC) with a 24 VAC secondary and is commonly specified at 40 VA, making it a direct fit replacement when your unit has lost stable 24-volt control power or is tripping due to a failing transformer. Confirm your unit wiring diagram and primary tap selection before installation to match the supply voltage and restore proper, reliable control operation.

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.
