Trane SWT0473 Safety Limit
The Trane SWT0473 Safety Limit is a Secondary High Safety Limit Switch designed for high-stakes temperature regulation in residential and commercial HVAC systems. Operating within a temperature range of 130°F to 300°F, this OEM replacement part acts as a critical fail-safe to prevent heat exchanger damage and system overheating. With a contact rating of 16A at 120 VAC and a maximum current capacity of 20A, it provides reliable interruption of the heating circuit when safety thresholds are breached. This limit switch features an automatic reset function, allowing the system to resume normal operation once internal temperatures return to a safe operating envelope. Engineered for compatibility with a wide range of Trane air handlers, furnaces, and package units, the SWT0473 serves as a direct Cross Reference for SWT00473. Its compact, durable design meets UL and CSA standards, ensuring it withstands the thermal stresses of continuous duty cycles in professional environments.
Key Benefits for HVAC Technicians- Precise Thermal Protection: Monitors internal cabinet temperatures to safeguard against blower failure or restricted airflow.
- OEM Compatibility: Genuine Trane HVAC Parts ensure exact fitment and terminal alignment without field modifications.
- Broad Application: Suitable for furnaces, heat pumps, and secondary high limit applications in multi-ton modular units.
- Voltage Versatility: Rated for up to 250 VAC, making it adaptable for various control circuit voltages.
- Durable Construction: Built to withstand commercial-grade thermal cycling in critical environments like data centers and hospitals.
- What is the difference between an primary and secondary limit switch? A primary limit is often the first line of defense integrated into the heat exchanger, whereas the Trane SWT0473 serves as a secondary high safety limit to monitor total cabinet or outlet air temperature.
- Does this switch require a manual reset? No, this specific model is an automatic reset limit switch, meaning it will close the circuit once the temperature drops below its differential threshold.
- Can this part replace a limit with a different temperature rating? No, for system safety, always match the specified temperature "Open" and "Close" points listed on the original equipment tag.
