Description
The Emerson Climate-White Rodgers 3L09-18 7.12″ Limit Switch is a temperature control and safety component used in heating and air handling systems. It operates by interrupting the electrical circuit when temperatures rise to 155F and restoring operation after temperatures decrease to 125F, helping regulate internal heat conditions during system operation. It is installed in furnaces, unit heaters, and HVAC systems, air circulation parts where temperature monitoring is required for safe efficiency. The overheating, supports controlled system cycling and assists in protecting internal components from excessive thermal conditions during extended heating operation.
