Trane RLY1172 Fan Relay

The Trane RLY1172 is a high-performance SP4T fan relay designed for precise fan motor control in commercial and residential HVAC systems. Built to handle 230V line voltage at a 16A FLA (Full Load Amperage) rating, this heavy-duty relay is activated by a standard 24V coil. The single-pole, four-throw configuration allows for versatile circuit switching, making it a critical component for managing multiple fan speeds or auxiliary equipment in air handlers and furnaces. As a genuine OEM replacement part (also identified as RLY01172), it ensures exact fitment and maintains the electrical integrity of Trane and American Standard units, including popular models like the TUD, TUX, and TDC series. The compact design and male quick-connect terminals simplify field installation, ensuring rapid restoration of airflow and system efficiency.

• Direct OEM Match: Drops into existing Trane HVAC mounting footprints without modification.
• High Current Capacity: Rated for 16A at 230V, providing robust switching for demanding fan motors.
• Versatile SP4T Switching: Facilitates complex fan speed logic or multi-circuit control from a single 24V signal.
• Field Reliability: Built for industrial-grade durability to withstand frequent cycling in high-demand environments.

What was the original part number for this relay?
The Trane RLY1172 was superseded by part number RLY01172. Both numbers represent the same technical specifications and are interchangeable for repairs.

Can I use this for a 120V fan motor?
While the relay is rated for 230V, it is frequently used in 120V applications (rated up to 48 RLA at 120V). Always verify your specific schematic requirements before installation.

Are the terminals compatible with standard spade connectors?
Yes, it features standard male quick-connect terminals for secure, vibration-resistant electrical connections.
