Description
The Emerson Climate-White Rodgers 3L09-24 Limit Switch is an electrical sensitive control component designed to monitor and regulate the operating conditions within heating equipment. Measuring 3.12 inches, this switch opens its electrical circuit at 190F, and automatically resets by closing at 170F as temperatures return to an acceptable range. It is installed in furnaces, unit heaters and other conduction-control components to prevent overheating. Within the system, the switch serves as a protective system that interrupts operation, when excessive heat is detected, supporting safe, and consistent performance across residential and light commercial HVAC systems applications.
