The Copeland 3L09-14 is an automatic reset limit switch designed for high-temperature protection in HVAC and heating equipment. This temperature control opens the circuit at 250°F and automatically resets (closes) at 210°F, helping prevent overheating while allowing normal operation to resume once temperatures drop. Built with a reliable bimetal disc, the 3L09-14 provides accurate and repeatable thermal response. Its compact design makes it suitable for installation in furnaces, unit heaters, and air handling systems where dependable limit control is required.
