Rheem-Ruud 42-23116-09 Sequencing Relay

For technicians servicing electric furnaces and air handlers, the Rheem-Ruud 42-23116-09 Sequencing Relay is an OEM replacement part designed to manage the staging of heating elements and blower motors. This 24V sequencing relay features a 3PST (Triple Pole Single Throw) configuration with normally open contacts, ensuring that high-amperage strips are energized in precise increments to prevent circuit overload and nuisance tripping of the main breaker. Engineered for high-duty cycles, it handles up to 25A resistive at 120/230V and includes a robust 24V thermal heater with a current draw of 0.2A steady state. The heat sequencer relay provides a reliable "on" timing of 10-30 seconds and an "off" delay of 30-60 seconds across all three poles, facilitating a smooth ramp-down of the system. Built with 1/4 inch quick-connect terminals and a standard two-hole angle bracket, this HVAC sequencer allows for rapid installation in tight control cabinets, maintaining OEM performance standards for Rheem and Ruud equipment.

• Multi-Stage Control: Triple-pole configuration allows for synchronized or staggered control of multiple heating elements or fan circuits.
• System Protection: Integrated timing delays prevent simultaneous high-load starts, reducing stress on the electrical service.
• Versatile Compatibility: Rated for use in 120V, 230V, and 460V applications, providing a wide range of industrial and residential utility.
• Exact OEM Fit: Eliminates the need for field modifications, fitting directly into the original mounting footprint of standard air handlers.

Is this a universal sequencer or brand-specific?
While the 42-23116-09 sequencing relay is a genuine Rheem-Ruud OEM part, its 3PST N/O configuration and 24V heater allow it to serve as a high-quality replacement in various electric heat applications requiring three-pole switching.

What are the timing specs for this relay?
The relay is calibrated for an actuation delay (ON) of 10 to 30 seconds and a de-actuation delay (OFF) of 30 to 60 seconds, which is the industry standard for preventing rapid cycling of furnace heating strips.

Can I use this for 460V systems?
Yes, the contacts are rated for 12.5A resistive at 460VAC, making it suitable for larger commercial air handlers as well as standard 230V residential units.
