White-Rodgers 3L02-180 Limit Switch Precision Thermal Calibration: Factory-set toThe White Rodgers 3L02 180 is a high limit snap disc manual reset limit switch designed for critical thermal protection in HVAC applications. This fixed temperature control features a 180 degree F cut out point, utilizing an open on rise switch action to break the electrical circuit when the system exceeds safe operating parameters. As a 60T15 series equivalent (specifically model 60T15 330536), it provides essential safety for furnaces and air
