Description
The Copeland 3L11-85 is a snap disc limit control calibrated to open on a temperature rise between 80°F and 90°F, making it well suited for fan and blower control, freeze protection sensing, and low-temperature limit applications in HVAC and refrigeration equipment. Snap disc controls operate as automatic single-pole switching devices that respond to surface or ambient temperature changes, snapping open or closed at a factory-set temperature threshold. The open-on-rise action of the 3L11-85 means the switch interrupts the circuit when the sensed temperature climbs to the set point, a configuration commonly used for freeze stats, cooling system controls, and equipment protection circuits where an elevated temperature condition should trigger a shutoff or alarm response. The disc mounts directly to a surface or duct wall, where it reads contact temperature for accurate and responsive control. Built to Emerson's White-Rodgers component standards, the 3L11-85 is a reliable drop-in replacement for OEM snap disc controls across a broad range of residential and commercial HVAC platforms.
