Description
The Rheem-Ruud PD425119 is an OEM 2-pole sequencing relay designed for use in electric heating systems where staged, sequential activation of heating elements is required. Operating on a 24-volt control circuit, this relay coordinates the timed energization of multiple heating stages, helping to reduce electrical demand spikes and extend the life of heating components.
Key Features
- OEM Rheem-Ruud replacement sequencing relay
- 2-pole design for dual-circuit sequential switching
- 24V control voltage for compatibility with standard low-voltage thermostat systems
- Provides staged activation of electric heating elements to manage load and reduce demand surges
- Direct OEM replacement ensures proper fit and function in compatible Rheem and Ruud electric furnace and air handler applications
Applications
- Rheem and Ruud electric furnaces
- Electric air handlers with sequenced heating elements
- Residential and light commercial electric heating systems
Why Choose OEM?
Using a genuine Rheem-Ruud OEM sequencing relay ensures your system operates exactly as designed — with proper timing, correct pole configuration, and reliable coil voltage. Aftermarket substitutes may not match the original timing characteristics, leading to premature element failure or nuisance tripping. The PD425119 is the correct replacement part, engineered to Rheem-Ruud factory specifications.
