Carrier HH18HV140 Auto Limit Switch 110°F-140°F

The Carrier HH18HV140 is an essential safety device in the Carrier HVAC system. It works as an automatic shut off switch to avoid overheating. It is installed within the system and constantly checks the temperature of the system. In case the temperature rises above the cut-out limit of 140°F, the HH18HV140 shuts off automatically helping protect the equipment. When the temperature returns back to the cut-in point of 110°F, the limit switch is released, enabling the system to run again. With built-in temperature control.
