Trane SWT2945 Limit Switch

Trane SWT2945 Limit Switch

The Trane SWT2945 is a professional-grade stainless steel limit switch engineered for high-limit protection in commercial HVAC systems, including air handlers, rooftop units, and fan coils. As a critical safety component, this 200°F high limit switch is designed to "open on rise," effectively interrupting the control circuit when air temperatures exceed the 200-degree threshold. This ensures system integrity and prevents potential damage to the heat exchanger or downstream components. The SWT2945 features a manual reset mechanism (200Op ManClose), requiring a technician to physically inspect the equipment and reset the switch after a trip. This fail-safe design is essential for identifying underlying airflow or combustion issues before resuming operation. Constructed with a durable stainless steel housing, it provides superior corrosion resistance in demanding mechanical environments. Rated for 240V and 25A with a 125VA pilot duty capacity, this OEM Trane replacement part ensures precise calibration and seamless integration with existing Trane HVAC controls.

Key Benefits
  • Enhanced Safety: The manual reset limit switch prevents automatic cycling under fault conditions, ensuring a technician clears the error.
  • Durable Construction: Features stainless steel housing for long-term reliability in high-moisture or corrosive HVAC environments.
  • Precise Thermal Response: Calibrated for a 200-degree opening temperature to protect sensitive furnace and air handler components.
  • High Electrical Rating: Capable of handling 25 Amp at 240V, compatible with a wide range of commercial pilot duty circuits.
  • Exact OEM Fit: Guaranteed compatibility with Trane SWT2945 specifications to maintain system UL listings and performance standards.
Common Questions

What does '200Op ManClose' mean for this switch?
It indicates that the switch is designed to open the circuit at 200°F and requires a manual operation to close (reset) the contacts after the temperature has dropped below the setpoint.

Is the Trane SWT2945 compatible with residential furnaces?
While primarily used in commercial air handlers and rooftop units, it can be used in any system requiring a 200°F high-limit trip with manual reset, provided the electrical ratings match.

Why would my limit switch trip frequently?
Common causes include restricted airflow from dirty filters, a failing blower motor, or oversized burners. Because this is a manual reset switch, it forces an inspection to prevent equipment fatigue.
