Product Overview
The Rheem 47-21900-13 is a manual reset limit switch designed for precise temperature-controlled applications. This switch operates in a normally closed, single-pole single-throw (SPST) configuration, providing reliable circuit protection by opening at a set temperature threshold.
Temperature Operation
- Closes at: -31°F
- Opens at: 150°F
This switch automatically opens the circuit when the temperature reaches 150°F, serving as a critical safety cutoff to protect equipment from overheating. Once tripped, the switch requires a manual reset before normal operation can resume, ensuring the underlying cause of the temperature fault is addressed before the system is restarted.

Manual Reset Safety Feature
Unlike automatic reset switches, this manual reset limit switch requires deliberate operator intervention to restore circuit continuity after a high-temperature event. This design adds an important layer of safety, preventing automatic system restart after a fault condition and ensuring proper inspection and diagnosis before resuming operation.
