Description
The Carrier HH18HA430 Auto Limit Switch is a safety component used in HVAC systems to control the temperature of the system with high efficiency. Having a width of 1.1” and a height of 0.8”, it has a cut out temperature of 130°F and cut in temperature of 100°F for optimum temperature control in heating as well as cooling equipment. This switch is used in furnaces and most Carrier HVAC systems to prevent the equipment from overheating. As it turns off the system when the set temperature is exceeded and starts the system when the temperatures are low, it improves the system performance and durability, and safety.
