Bard 8402-120 L210 Manual Reset Limit Control Switch

The Bard 8402-120 is an OEM manual reset limit control designed to protect Bard wall-mount HVAC heating equipment from potentially dangerous overheating conditions. This L210-rated limit switch is engineered to open the heating circuit when air temperatures reach approximately 210°F, immediately shutting down heat operation to prevent damage to the heat exchanger, cabinet components, and surrounding areas.

Key Features:

• Manual reset design requires technician intervention to restore operation, ensuring the cause of overheating is addressed before equipment restarts
• L210 temperature rating provides high-temperature protection at 210°F setpoint
• Direct OEM replacement part ensures proper fit and function in Bard wall-mount systems
• Critical safety component for electric heat sections and air handler applications
• Designed specifically for Bard HVAC equipment specifications and operating parameters

Manual reset limit controls are essential safety devices in HVAC systems, requiring a technician to physically reset the switch after a trip event. This design prevents automatic restart and ensures that airflow restrictions, failed blowers, or other fault conditions are properly diagnosed and corrected before the unit returns to service. Commonly used in Bard wall-mount package units and heat pump systems.
