Description
The Emerson Climate-White Rodgers 3L09-7 3.12″ Limit Switch is a temperature-sensitive safety control component used to interrupt electrical operation when internal equipment temperatures reach unsafe levels in HVAC systems. Featuring a bimetal disc switching mechanism, the control opens the circuit at 175F and automatically resets when temperatures decrease to 145F for repeated cycling operation. Positioned near heating sections or heat exchangers, it monitors temperature changes directly within the equipment cabinet during furnace operation. The compact configuration allows compatibility with confined control spaces while maintaining thermal protection and regulated temperature.
