Rheem-Ruud 47-25349-11 General Purpose Limit Switch Overview
The Rheem-Ruud 47-25349-11 is a board-mounted, general-purpose limit switch engineered to protect HVAC equipment from overheating conditions. With a fixed open temperature of 145°F and a fixed close temperature of 125°F, this switch automatically interrupts the circuit when unsafe temperatures are detected and resets once conditions return to normal — no manual intervention required. The black/red color coding simplifies identification and wiring during installation and service.
Key Features
- Fixed open temperature: 145°F — reliably trips to protect equipment from overtemperature conditions
- Fixed close temperature: 125°F — automatically resets when temperature drops back to safe operating range
- SPST Normally Closed (NC) switch configuration for fail-safe circuit protection
- Auto reset operation eliminates the need for manual reset after a trip event
- 3″ insertion length for proper sensing depth within the airstream or heat exchanger
- Board-mounted design for direct integration with furnace or air handler control boards
- Black/Red color-coded leads for fast, accurate wiring identification
- OEM replacement part for compatible Rheem and Ruud heating systems
