Bard 8402-154 L165-30 Limit Control Switch Exposed Face Auto Reset Orange

The Bard 8402-154 is an OEM exposed-face limit control switch designed to protect Bard wall-mounted HVAC equipment from overheating conditions. This L165-30 rated safety device opens the electrical circuit when temperatures reach approximately 165°F and automatically resets when temperatures drop by approximately 30°F, helping prevent nuisance lockouts while safeguarding heat exchangers, blowers, and surrounding components.

Key Features:

• L165-30 temperature rating: opens at 165°F, closes at approximately 135°F
• Exposed-face design for direct airstream sensing
• Automatic reset operation for convenient system protection
• Orange color-coded identification for easy field recognition
• Factory-specified replacement part for Bard HVAC systems
• Single-pole switch configuration for safety circuit control

This limit control is a critical safety component that monitors airstream temperature and interrupts operation when dangerous overheating occurs due to restricted airflow, filter blockage, or abnormal system operation. The automatic reset feature allows the system to resume normal operation once temperatures return to safe levels, eliminating the need for manual intervention. Always verify compatibility with your specific Bard model number before ordering to ensure proper temperature rating, mounting configuration, and reliable factory-specified performance.
