Bard 8407-043BX - 60VA Control Transformer

The Bard 8407-043BX is an OEM control transformer rated at 60VA with multi-tap primary inputs for 480, 240, or 208 volts, designed to step incoming line voltage down to the low-voltage power used by Bard wall-mount HVAC control circuits. If your unit has weak or intermittent 24-volt control power, nuisance control dropouts, or a failed transformer, replacing it with the correct Bard part helps restore reliable operation for relays, contactors, and control boards while maintaining proper electrical fit within the original control compartment. Always confirm your unit data plate voltage and verify the primary tap connections match your supply voltage before installation.

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.
