Description
The Rheem-Ruud 47-25349-13 is an OEM general purpose limit switch engineered for board-mounted temperature control applications in Rheem and Ruud heating systems. Color-coded in yellow and red for quick field identification, this switch provides reliable over-temperature protection with automatic reset capability.
How It Works
This SPST normally closed (NC) limit switch monitors supply-air or heat exchanger temperatures and interrupts the circuit when unsafe temperatures are detected. At 190°F, the switch opens to shut down the burner or heating element. Once temperatures fall back to 170°F, the auto-reset function automatically restores the circuit — no manual intervention required.
