Aaon P91330 High Limit Switch 210°F-40°F

The Aaon P91330 High-Limit Switch is used to prevent HVAC systems from getting overheated. It has a temperature range of 210°F – 40°F and the insert length is 7 inches. When the temperature exceeds 210°F, the switch goes off and cuts power to the heating element or compressor. When the temperature falls below the reset point, the switch is in the closed position to continue the operation. This basic safety feature is used extensively in furnaces, boilers and other heating appliances to prevent fire, parts damage and costly repairs. It has an automatic reset feature that ensures that the system is running all the time.
