Reznor 50418 Auto Limit Switch 125°F-145°F

The Reznor 50418 Auto Limit Switch is designed to maintain the internal temperature of HVAC systems to safe and efficient levels for the operation of the system. It is activated when the temperature is between 125 and 145 degrees Fahrenheit. When the set temperature is attained, the auto reset halts the power supply to avoid overheating and then resumes as the temperature drops to normal. This limit switch is usually applied in heaters, furnaces, and other HVAC equipment to ensure better performance. The advantages include increased safety of the equipment and decreased chances of heat-related problems in the commercial and residential heating systems.
