Copeland Comfort Control (White Rodgers) 90-486 Fan Relay

The White-Rodgers 90-486 Fan Relay is a specialized SPNO/SPNC enclosed relay engineered for heavy-duty switching in commercial HVACR and industrial motor control applications. This heavy-duty industrial power relay operates reliably at a maximum voltage rating of 277V, providing the versatile contact configuration needed for both fan sequencing and high-current power switching. As a trusted HVAC mechanical relay, the 90-486 features an enclosed design to protect internal components from dust and debris, ensuring consistent performance in demanding environments. Whether you are performing a White-Rodgers 90-486 replacement or installing a new fan control system, this unit offers the electrical integrity required for 24VAC coil circuits and line voltage loads. Technical professionals utilize this relay for its durability and precise switching capabilities in residential and light commercial air handling units.

• Universal Application: The SPNO/SPNC (Single Pole Normally Open / Single Pole Normally Closed) configuration allows for flexible wiring in cooling, heating, or multi-speed fan circuits.
• High Voltage Capacity: Rated for systems up to 277V, making it compatible with 120V, 208V, 240V, and 277V industrial power supplies.
• Enclosed Protection: The rugged housing prevents contact contamination, extending the service life of the fan control relay.
• Heavy-Duty Switching: Designed to handle inductive and resistive loads typical of blower motors and industrial machinery.
• RoHS Compliant: Built to modern safety and environmental standards for easy integration into professional specifications.

What is the coil voltage for the 90-486?
The White-Rodgers 90-486 typically utilizes a 24V AC control coil, making it compatible with standard HVAC transformers and thermostats.

Can this relay replace an open-frame type?
Yes, provided the electrical ratings match, this enclosed model is often a superior choice as it protects the contacts from environmental buildup.

Is this relay suitable for 277V lighting circuits?
While primarily used for fan and motor control, its 277V rating and heavy-duty contacts allow it to switch various high-voltage resistive and inductive loads within its amperage specifications.
