Rheem-Ruud 47-101529-09 Low Limit Switch
The Rheem-Ruud 47-101529-09 is an OEM low limit temperature control switch designed to safeguard HVAC equipment against dangerously low operating temperatures. When supply air or coil temperatures drop to the trip point, this switch opens the control circuit to prevent freeze damage and protect system components. Once temperatures recover, the switch automatically resets, restoring normal operation.
