White-Rodgers 90-362 Fan Relay
The White-Rodgers 90-362 Fan Relay is a heavy-duty, Type 184 switching solution engineered for high-demand HVACR applications. As a 120V SPST N/O fan relay, it provides reliable control for indoor blower motors, unit heaters, and general-purpose switching in both heating and cooling systems. The 120 VAC coil is designed for 50/60 Hz operation, featuring a 2000 Ohm DC resistance and a nominal current draw of 25 mA. With an inrush rating of 4 VA and a steady 3 VA nominal power consumption, this enclosed relay ensures stable performance without excessive load on control circuits.
Designed for professional contractors, the White-Rodgers 90-362 features 1/4" quick-connect terminals for rapid installation. Its compact, totally enclosed housing prevents dust ingress, and it is rated for a wide temperature range from -40°F to 150°F. The electrical configuration handles significant inductive loads, with ratings of 12A at 125 VAC and 8A at 250 VAC, while the resistive rating reaches 18A at 277 VAC. This SPNO relay is a versatile industry standard for modernizing older air handlers or replacing failed fan center components.
Key Benefits- High-Capacity Switching: Rated for up to 12A inductive at 125V, making it ideal for standard blower motor applications.
- Universal Compatibility: Standard Type 184 footprint allows for easy replacement of existing 120V fan control relays.
- Quiet Operation: Precision-balanced solenoid coil reduces acoustic noise during startup and continuous operation.
- Durable Enclosure: Totally enclosed design protects internal contacts from debris and oxidation in harsh mechanical environments.
- Flexible Mounting: Operates efficiently in any orientation for tight cabinet configurations.
Is the White-Rodgers 90-362 compatible with 24V thermostat circuits?
This specific model features a 120V coil. If you are switching the relay using a standard 24V thermostat signal, you will need a 24V coil alternative (such as the 90-360) or an intermediate transformer. This 90-362 is intended for line-voltage control signals.
What is the difference between SPST N/O and SPDT relays?
The 90-362 is a Single Pole Single Throw, Normally Open relay. This means it has one set of contacts that remain open until the coil is energized, effectively acting as a simple on/off switch for a single load.
Can I use this relay for resistive heating elements?
Yes, the 90-362 is rated for 18A resistive at 277 VAC, making it suitable for smaller electric heat strips or infrared heaters within those parameters.
