Description
The Lennox 45H83 Auto Limit Switch is a protective mechanism installed on residential and commercial heating, ventilating, and air conditioning systems. They protect your furnace from high temperatures by turning off your heating system if it gets too hot; usually between 200°F and 230°F. This particular round limit switch comes with a 3/8 Inch NPT which makes it versatile for use in a number of HVAC systems since it only needs a 240V voltage source, making it a reliable solution if you want to avoid overheating and subsequent damage to furnaces.
