Description
The Bard HVAC 8406-037BX is an OEM manual reset temperature switch rated to trip at 220°F, engineered to provide dependable high-limit protection in Bard heating and cooling equipment. When the monitored temperature reaches the 220°F setpoint, the switch opens the circuit and locks out operation until a technician manually resets it — preventing equipment damage caused by sustained overtemperature conditions.

Application

The manual reset function ensures that the root cause of an overtemperature event is investigated and corrected before the unit is returned to service.
