Product Overview
The Rheem 47-21711-11 is an automatic reset limit switch designed for use in heating systems requiring reliable high-temperature protection. With a temperature range of 160°F to 180°F, this switch provides precise thermal cutoff control to safeguard your HVAC equipment from overheating conditions.
Key Specifications
- Manufacturer Part Number: 47-21711-11
- Temperature Rating: L180-20F (Opens at 180°F, resets at 160°F)
- Reset Type: Automatic Reset
- Switch Configuration: Single Pole, Single Throw (SPST)
- Default State: Normally Closed (NC)
- Insert Length: 7 inches
How It Works
This limit switch operates in a normally closed state under standard conditions, allowing the heating system to function normally. When temperatures reach the upper limit of 180°F, the switch automatically opens to interrupt the circuit and protect the system. Once temperatures drop back down to 160°F, the switch automatically resets itself — eliminating the need for manual intervention.
Design & Construction
The switch features a 7-inch insert, making it suitable for installations where the sensor must extend into ductwork or heat exchangers to accurately monitor air or surface temperatures. The SPST configuration ensures straightforward wiring and compatibility with standard limit switch circuits found in Rheem and compatible heating systems.
Compatible Applications
This limit switch is a genuine Rheem OEM replacement part, making it an ideal choice for maintaining the performance and safety standards of Rheem furnaces and heating equipment. Always verify compatibility with your specific unit model before installation.
