Bard 8402-049BX Limit Control 150-115 Temperature Safety Switch

The Bard 8402-049BX is an OEM limit control designed to protect Bard HVAC equipment by monitoring supply air temperature and preventing overheating conditions. This automatic reset temperature safety switch is calibrated to open the circuit at approximately 150°F and reclose when temperatures drop to around 115°F, providing a 35°F differential for reliable system protection.

Key Features:

• Opens at 150°F, closes at 115°F for optimal temperature regulation
• Automatic reset design prevents nuisance lockouts while maintaining safety
• Protects heaters, blowers, and surrounding components from overheating
• Prevents damage caused by restricted airflow or abnormal operation
• Precision-engineered for demanding HVAC conditions
• Direct OEM replacement for Bard wall mount and packaged HVAC units

This limit control is essential for maintaining safe operating temperatures in Bard heating and cooling systems. When abnormal high temperatures are detected due to restricted airflow or system malfunction, the limit automatically opens the heating circuit to prevent damage, then allows operation to resume once temperatures return to a safe range. Matching the exact Bard part number ensures proper temperature rating, mounting fit, and reliable factory-specified protection.
