Application
This limit switch is a direct OEM replacement for Rheem and Ruud heating systems. It is commonly used as a high-limit safety control in gas furnaces and air handlers to protect heat exchangers and system components from overheating. The SPST normally closed design ensures the circuit remains complete during normal operation and interrupts it only when an unsafe temperature is detected.
