Bard 8402-078BX L175-30 Limit Control with 7" Capillary

The Bard 8402-078BX is an OEM replacement limit control designed to protect HVAC equipment from overheating by opening the circuit when temperatures exceed safe operating limits. This L175-30 style limit control is factory-calibrated to open at 175°F and automatically reset (close) at 155°F, providing a 20°F differential for reliable temperature management in heating systems.

Key Features:

• Opens at 175°F, closes at 155°F (20°F differential)
• 7-inch capillary tube for flexible mounting and precise temperature sensing
• Automatic reset operation for continuous protection
• OEM Bard part ensures proper fit and performance in Bard wall-mount HVAC units
• Prevents system damage by interrupting operation during overheat conditions

This limit control is a critical safety component in electric heat sections, air handlers, and furnace applications where temperature rise must be controlled. The 7-inch capillary allows for installation flexibility while maintaining accurate temperature sensing. Commonly used in Bard wall-mounted heating and cooling equipment to maintain system reliability and protect against thermal overload conditions.
