Bard 8402-141BX L160-7.0 Two-Pole Limit Control Switch

The Bard 8402-141BX is an OEM two-pole limit control designed to protect Bard HVAC heating equipment from overheating conditions. This temperature-sensing safety switch monitors supply air or surface temperature and opens the control circuit when the preset temperature threshold is reached, helping to safeguard heat exchangers and system components.

Key Features:

• L160-7.0 rating: Opens at approximately 160°F, automatically resets when temperature drops by 7°F differential
• Two-pole (DPST) configuration for enhanced control circuit protection
• Automatic reset design eliminates manual intervention after temperature normalizes
• Bimetal disc snap-action construction provides reliable temperature sensing
• Designed specifically for Bard wall-mount and package HVAC units

This limit control is essential for preventing damage from restricted airflow, dirty filters, or blower motor failures. When troubleshooting short cycling on heat or repeated high limit trips, replacing a worn or out-of-calibration limit switch with the correct Bard 8402-141BX ensures proper safety operation and system longevity.
