Product Overview
The Rheem 47-21711-20 is a Single-Pole Single-Throw (SPST), Normally Closed (N/C), Auto-Reset Limit Switch designed for reliable temperature control and safety protection in heating systems.
Key Specifications
- Type: SPST (Single-Pole Single-Throw)
- Configuration: Normally Closed (N/C)
- Reset Type: Auto-Reset (A/R)
- Opening Temperature: 110°F
- Closing Temperature: 95°F
- Component Type: Limit Switch
- Brand: Rheem
- Part Number: 47-21711-20
How It Works
This limit switch operates in a normally closed position, meaning the circuit remains closed under normal operating conditions. When the temperature reaches the opening threshold of 110°F, the switch opens to interrupt the circuit and protect the system. Once temperatures drop back down to 95°F, the switch automatically resets and closes the circuit, restoring normal operation without manual intervention.
Auto-Reset Functionality
The auto-reset feature eliminates the need for manual resetting after the switch has been triggered. Once system temperatures return to the safe closing threshold of 95°F, the limit switch automatically restores circuit continuity, ensuring minimal downtime and consistent system performance.
Compatibility
This is a genuine Rheem OEM replacement part, engineered to meet the exact specifications required for compatible Rheem heating equipment. Always verify your equipment's model number and part requirements before purchasing to ensure proper fit and function.
