Bard 8401-006BX - 2-Pole 20A Contactor (24V Coil)

The Bard 8401-006BX is an OEM 2-pole contactor designed to handle 20 amp switching with a 24V coil, making it a common replacement for restoring reliable call-for-cooling or call-for-heat operation in Bard wall-mount and packaged HVAC equipment. This control component is responsible for pulling in and delivering power to major loads like the compressor and condenser fan when the low-voltage signal is present, so a weak or chattering contactor can cause intermittent starts, nuisance shutdowns, or no operation. Replacing with the correct Bard part helps ensure proper electrical ratings and dependable engagement, and this boxed part is listed as the replacement for earlier Bard numbers including 8401-006 and S8401-006.

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.
