Rheem-Ruud 47-23433-05 Relay

The Rheem-Ruud 47-23433-05 Relay is a specialized delay on break time delay relay engineered to stabilize performance in commercial and residential HVAC applications. Purpose-built to function as an anti-short cycle timer, this component protects the compressor and other critical system elements by enforcing a fixed 0.75-minute (45-second) delay period after power is interrupted or the control circuit opens. Rated for 18-30 VAC operation with a 1A steady-state current capacity, it ensures that refrigerant pressures equalize before a restart, mitigating mechanical stress and preventing premature motor failure. This genuine OEM replacement features industry-standard 1/4-inch quick connects for straightforward integration into existing control circuits. Whether you are troubleshooting a Rheem central air conditioner that is short-cycling or servicing a high-demand Ruud heat pump, this low voltage time delay provides the precise timing required for reliable operational sequencing and system longevity in harsh site conditions.

• Anti-Short Cycle Protection: Prevents rapid compressor cycling by maintaining a 45-second wait time, significantly reducing current inrush and thermal stress.
• Universal Compatibility: Designed for use across Rheem, Ruud, and WeatherKing platforms requiring a 24V control signal.
• Standardized Installation: Utilizes 1/4-inch male spade terminals for quick connection to standard field wiring.
• Fixed Timing Accuracy: Eliminates the need for field adjustments with a factory-preset 0.75-minute delay on break.
• OEM Durability: Built to original equipment specifications to handle the environmental and electrical fluctuations of modern HVAC systems.

What is the purpose of a delay on break relay?
It prevents the HVAC system from restarting immediately after loss of power or a thermostat signal, allowing system pressures to stabilize and protecting the compressor from damage.

Can I use this relay for both heating and cooling equipment?
Yes, this HVAC relay part is suitable for air conditioners, heat pumps, and furnaces operating within the 18-30 VAC range.

How do I wire the 47-23433-05?
Refer to your specific unit's wiring diagram; typically, it is wired in series with the contactor coil or control circuit to interrupt power during the delay period.
