Bard 8402-165BX L250-3F Auto Reset Limit Switch

The Bard 8402-165BX is an OEM automatic reset limit switch designed to protect HVAC heating equipment from overheating by monitoring supply air temperature. This limit control features an L250-3F rating, meaning it opens the circuit at approximately 250°F and automatically recloses when the temperature drops by 3°F differential.

Key Features:

• L250-3F temperature rating: opens at 250°F, closes at 247°F
• Automatic reset functionality for reliable operation
• OEM Bard replacement part for proper fit and function
• Prevents heat exchanger damage and cabinet overheating
• Designed for Bard wall mount and packaged HVAC systems

This high-temperature limit switch is a critical safety component that cuts power to the heating circuit when excessive temperatures are detected, then automatically restores operation once safe temperatures return. The "BX" suffix indicates this part is factory-packaged in a box for individual sale.
