Lennox 73W19 Limit Switch 155°F 30V

The Lennox 73W19 Limit Switch is a safety and efficiency control component that is specifically developed to be used into HVAC systems. While it operates optimally at 155°F, this limit switch helps to shut down electrical circuits whenever the temperature of the heating systems goes above the specified limit, to avoid instances whereby heating systems get destroyed by excess heat. It reboots at 125°F, so it does not hazard of overheating while providing the better temperature regulation. This switch is especially helpful in different Lennox heating models, which are effective in commercial and residentialuse. It automatically resets itself and the cycle delays and reboots result in less requirement of manual interferences cutting back on maintenance.
