Bard 8402-200BX is an OEM one-shot limit control rated to open at 150 degrees F, used as a high-temperature safety in Bard wall-mounted HVAC equipment and electric heat applications. When abnormal heat buildup occurs, this temperature limit helps protect key components by interrupting the circuit and requiring replacement after it trips, restoring proper safety operation once the underlying airflow or heating issue is corrected. If you are replacing a failed safety limit or troubleshooting nuisance shut downs, match this part number to your unit literature and verify the original cutout temperature before installation to maintain factory protection levels.
* Orders less than $50 may incure a minimum order fee.
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.
