Bard 8402-221BX - Limit Control Switch
Bard 8402-221BX is an OEM limit control (L140-5.5) used in Bard wall-mounted HVAC equipment to monitor operating temperature and open the control circuit if an over-temperature condition occurs, helping protect heaters and other components during heating operation. This boxed, factory-correct safety switch is intended as a direct replacement for the original limit control so your unit can cycle properly without nuisance trips or unsafe overheating. Match the part number exactly and verify your unit model and wiring layout before installation, since limit controls are application-specific and are critical to safe 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.
