Bard 8402-138BX is an OEM high-limit temperature control rated at 240 degrees F with a one-shot safety cutout, supplied in a protective box enclosure. This control is used to help prevent overheating by opening the safety circuit when abnormal temperatures are reached, protecting key components and supporting safe operation in Bard HVAC equipment. It is a direct-fit Bard replacement part intended to match the original control style and temperature rating, so verify your unit model and wiring layout before ordering to ensure proper application and safe, code-compliant service.

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.
