The White Rodgers 03L11-150 series bimetal disc thermostats are designed for use in a wide range of appliance and HVAC applications. These thermostats utilize a bimetallic strip that bends or flexes in response to temperature changes, triggering an electrical contact to open or close. They feature stainless steel mounting brackets, quick connect terminations, and automatic reset functionality. The 03L11-150 specifically operates with an open-on-rise action, meaning the circuit opens as the temperature increases, and is suitable for applications requiring precise temperature regulation and safety control.
