Trane RLY1663 Relay
The Trane RLY1663 Relay is a heavy-duty, field-proven HVAC enclosed relay designed for demanding commercial and residential applications. Operating at a 240V coil voltage with a 5A contact rating, this 3PDT general-purpose relay provides critical isolation and switching for complex circuitry in air conditioners, heat pumps, and furnaces. The unit features fine wire gauge coils and a coil-molded polyester housing to resist environmental degradation and ensure coil integrity. With its flange enclosure and standard 0.250-inch male quick-connect terminals, it allows for streamlined integration and a secure physical mount. As a genuine Trane OEM part, the RLY1663-Trane replacement facilitates reliable communication between low-voltage controls and high-voltage components like blower motors and heat strips, maintaining precise timing and sequence of operations. This unit is professionally rated for 240VAC at 5 amps and is UL-recognized for safety and RoHS-compliant for environmental standards.
Key Benefits:- Enhanced Durability: Features silver contacts and skeined coils to resist pitting and electrical wear during high-cycle heating and cooling phases.
- Universal Mount Enclosure: The enclosed 3PDT relay design protects internal components from dust and debris while the flange allows for easy surface mounting.
- OEM Compatibility: Replaces legacy part numbers including RLY01663 and RLY 1663, ensuring an exact fit without manual modifications.
- High Dielectric Strength: Built with molded polyester to provide superior electrical insulation across its 240V operational range.
- What is the primary function of the RLY1663 in a Trane system? It typically acts as a fan relay or sequencer relay, switching high-voltage power to the blower motor or auxiliary heaters when triggered by the 24V thermostat signal.
- Can this relay be used in 120V circuits? While the contacts are rated for various loads, the RLY1663 requires a 240V coil source to actuate properly. Always verify the control voltage on your schematic before installation.
- Does this include the external wiring harness? This specific SKU is for the enclosed relay assembly itself; existing wiring and connectors should be inspected for corrosion before being reattached to the quick-connect terminals.
