Utica-Dunkirk 127000010 Limit Switch 210°F Open 170°F-Close

The Utica Dunkirk 127000010 Limit Switch is a temperature-sensitive safety part used in HVAC systems. It is designed to open at 210°F and close at 170°F to prevent overheating by cutting off electrical flow when the temperature exceeds safe limits and then reestablishing operation when cooling occurs. This switch is commonly installed in heating units to provide a safety and efficiency enhancement by maintaining optimal thermal control. Its precise thermal response protects components, limits damage, and limits variability in performance, making it the necessary part for durable temperature control in residential or commercial heating applications.
