Carrier HH18HA120 Temperature Switch 120°F-30°F

The Carrier HH18HA120 is a temperature switch, a safety mechanism integrated into Carrier HVAC systems. As a protecter of the device it also controls temperature by cutting off the electrical current if the circuit reaches certain temperature point. This limit, in the case of the HH18HA120, is 90°F (120°F - 30°F). By providing a means of switching off the power supply to the compressor or other heating element the high temperature switch protects the equipment from possible damage due to high temperature levels. These small switches are essential in the safe and proper functioning of your Carrier HVAC system. It is compatible with different Carrier equipment and is set with a default temperature range suitable for certain processes in the system.
