Description
The Trane CNT04822 Bi-Metal Disc Limit Control is a safety temperature switch used, in heating and cooling equipment to monitor internal operating heat levels. It uses a disc element that responds to excessive by opening the electrical circuit, stopping system operation to prevent overheating damage. Mounted in packaged and rooftop units, it is typically positioned in the airflow or heat-exchanger area to detect abnormal temperature rise. This control support protects essential components such as coils and heat exchangers ensuring safe shutdown during fault conditions and supporting operation of the HVAC system in residential and commercial applications.
