Daikin-McQuay 90370 Relay
The Daikin-McQuay 90370 Relay is a heavy-duty 24V SPDT fan relay engineered for precise switching in commercial and residential HVAC systems. Designed with a single pole double throw (SPDT) configuration, this component provides essential control over fan motor speeds and auxiliary circuits, ensuring efficient air handlers and furnace operations. As a veteran-preferred HVAC motor relay, it serves as a direct drop-in for Daikin 90370 and McQuay 90370 part numbers, often cross-referencing to MARS 90370 and Supco 90370 units. This general purpose fan relay features 0.25-inch quick-connect terminals for simplified field wiring and a standard tab bracket for non-positional mounting. With a robust coil rated for 24VAC and contacts capable of handling inductive loads (typically 12 FLA at 125VAC), this HVAC part maintains reliable switching performance under high-demand operational cycles. Technicians trust this replacement relay for its consistent drop-out voltage and compliance with UL/CSA standards, providing a dependable solution for circuit isolation and multi-speed blower management.
Key Benefits- Universal Compatibility: Seamlessly replaces Daikin-McQuay 90370 and similar 24V SPDT configurations from MARS and Supco.
- Enhanced Circuit Control: The SPDT configuration allows for alternating control between two separate circuits, ideal for multi-speed fan applications.
- Simplified Installation: Equipped with 0.25-inch quick-connect terminals and a universal mounting tab for rapid field replacement.
- Industrial Durability: Built to withstand the electrical rigors of HVAC/R environments with a high FLA rating for fan motor control.
Is the 90370 relay compatible with other brands?
Yes, while manufactured for Daikin-McQuay, this is a universal 24V SPDT relay that commonly replaces MARS 90370, White-Rodgers 90-370, and Supco 90370 models in various HVAC applications.
What are the contact ratings for this fan relay?
This relay typically supports 12 FLA / 60 LRA at 125VAC and 8 FLA / 48 LRA at 250VAC, making it suitable for most standard blower motors and inductive loads.
Can I mount this relay in any orientation?
Yes, the Daikin-McQuay 90370 features a non-positional design with a standard tab bracket, allowing for secure installation in any orientation within the control cabinet.
