Reznor 85449 Auto Limit Switch 140°F-200°F

The Reznor 85449 Auto Limit Switch is a temperature-sensitive safety control that assists in controlling the amount of heat by altering its contact state as temperatures vary. When the internal temperature exceeds 140°F it opens the control circuit and closes it as the temperature decreases to 200°F when operating in furnaces and packaged HVAC systems. The equipment is fitted in a position where the heat has to be monitored and connected to the control circuitry as per specifications. This limit switch can be used to protect components by responding to temperature changes to prevent overheating.
