Description
The Bard HVAC 8402-068 is an OEM automatic reset limit switch designed to provide dependable high-temperature protection in Bard heating and HVAC equipment. Featuring a 7″ sensing element, this limit switch opens at 260°F and automatically resets once temperatures drop by 30°F, helping safeguard heat exchangers, burners, and associated components from damaging overtemperature conditions.
Product Overview
Limit switches are a critical safety component in forced-air heating systems. When supply air temperatures exceed the rated setpoint, the limit switch interrupts the burner circuit to prevent overheating. The auto-reset function restores normal operation once temperatures return to a safe range, minimizing downtime and service calls.
