Product Overview
The Rheem 470018 is a 145°F automatic reset limit switch designed for reliable thermal protection in heating systems. This normally closed, single-pole single-throw (SPST) switch automatically resets once the temperature drops below the set point, eliminating the need for manual intervention after a thermal trip event.
Key Specifications
- Part Number: 470018
- Brand: Rheem
- Set Point Temperature: 145°F
- Differential: 20°F (resets at approximately 125°F)
- Reset Type: Automatic (Auto Reset)
- Switch Configuration: Single-Pole Single-Throw (SPST)
- Normal Switch State: Normally Closed (NC)
How It Works
This limit switch operates in a normally closed state, meaning the circuit remains complete during standard operating conditions. When the temperature reaches the 145°F trip point, the switch opens to interrupt the circuit and protect the system from overheating. With a 20°F differential, the switch automatically resets and closes the circuit once temperatures fall back to a safe level, restoring normal operation without manual reset.
Application
This OEM Rheem limit switch is engineered for use in Rheem heating equipment where automatic thermal cutoff protection is required. It is a direct replacement component ideal for service technicians and HVAC professionals maintaining or repairing Rheem heating systems.
