Description
The Bard HVAC 8402-078BX is a genuine OEM replacement limit control designed to protect heating equipment from overtemperature conditions. Engineered to the exact specifications of original Bard equipment, this snap-disc style limit switch provides reliable high-limit protection and helps ensure safe, efficient system operation.
How It Works
This limit control monitors equipment temperature and automatically interrupts the circuit when a preset high-limit threshold is reached. Once temperatures return to a safe operating range, the control resets — preventing nuisance shutdowns while still guarding against dangerous overheating conditions.
