Product Overview
The Rheem 47-21900-06 is a manual reset limit switch designed for reliable temperature-based circuit protection in heating and HVAC applications. This switch operates in a normally closed (NC) configuration and features a Single Pole Single Throw (SPST) design for straightforward integration into control circuits.
Temperature Operation
- Opens at: 180°F — disconnects the circuit when temperature reaches this threshold to prevent overheating
- Closes at: -31°F — ensures the circuit remains closed under normal and low-temperature operating conditions
Manual Reset Functionality
This limit switch features a manual reset mechanism, meaning that once the switch has opened due to a high-temperature condition, it must be manually reset before the circuit can be restored. This design provides an added layer of safety by requiring a deliberate action to resume operation, helping to identify and address the root cause of the temperature fault before restarting the system.
