Product Overview
The Rheem 47-20045-03 is an automatic reset limit switch designed for use in heating systems where precise thermal protection is required. This switch provides reliable over-temperature protection, automatically resetting once safe operating temperatures are restored.
Key Specifications
- Manufacturer: Rheem
- Part Number: 47-20045-03
- Switch Type: Limit Switch
- Reset Type: Auto Reset
- Switch Configuration: DPST (Double Pole, Single Throw)
- Normal State: Normally Closed (NC)
- Trip Temperature: L170°F
- Reset Differential: 40°F
How It Works
This normally closed limit switch remains in the closed (active) position during normal operation, allowing current to flow through the circuit. When the sensed temperature reaches the trip point of 170°F, the switch opens to interrupt the circuit and protect the system from overheating. Once the temperature drops by the 40°F differential (to approximately 130°F), the switch automatically resets to its closed position — requiring no manual intervention.
Switch Configuration
The DPST (Double Pole, Single Throw) configuration allows this limit switch to simultaneously control two separate circuits with a single switching action, making it well-suited for applications requiring dual-circuit thermal protection within a single heating unit.
Compatibility
This is a genuine Rheem OEM replacement part, engineered to meet the exact specifications of compatible Rheem heating systems. Always verify your equipment's model and part number before ordering to ensure proper fitment and safe operation.
