Product Overview
The Rheem 47-21663-01 is a precision-engineered limit switch designed for reliable thermal protection in heating systems. This component serves as a critical safety device, automatically monitoring and responding to temperature conditions to protect your equipment from overheating damage.
Key Specifications
- Part Number: 47-21663-01
- Switch Type: Single-Pole, Single-Throw (SPST)
- Circuit Configuration: Normally Closed (N/C)
- Reset Type: Automatic Reset (A/R)
- Opening Temperature: 140°F
- Closing Temperature: 130°F
- Model Designation: L140-10F
How It Works
This limit switch operates in a Normally Closed position under standard conditions, allowing the circuit to function as intended during normal operation. When temperatures reach the opening threshold of 140°F, the switch automatically opens the circuit, interrupting operation to prevent overheating. Once temperatures drop back down to 130°F, the switch automatically resets and closes the circuit, restoring normal system operation — no manual intervention required.
Features & Benefits
- Automatic Reset: Eliminates the need for manual resetting after the switch trips, reducing downtime and service calls
- Normally Closed Design: Ensures the system remains operational under safe temperature conditions
- SPST Configuration: Simple and reliable single-pole, single-throw switching for straightforward integration
- Precise Temperature Differential: A 10°F differential between opening (140°F) and closing (130°F) temperatures ensures stable, consistent performance
- OEM Rheem Part: Manufactured to exact Rheem specifications for guaranteed compatibility and performance
Compatibility
This is a genuine Rheem OEM replacement part engineered to meet the exact standards of your Rheem heating system. Always verify your equipment's model and part number against your system's documentation or existing component to ensure proper fitment before installation.
