Rheem-Ruud 425086 24V SPST N/O Sequencing Relay

Description

Rheem-Ruud 425086 24V SPST N/O Sequencing Relay

The Rheem-Ruud 425086 is a 24-volt, single pole single throw (SPST), normally open (N/O) sequencing relay engineered for use in electric furnaces and air handler heat strip applications. Designed as a genuine OEM replacement component, this relay ensures proper staging of electric heating elements to deliver consistent, controlled heat output while protecting the system from electrical overload.

How It Works

Sequencing relays are critical components in electric heating systems. When the thermostat calls for heat, the 24V control signal energizes the relay coil, closing the normally open contacts and activating the heating element in sequence. This staged approach prevents simultaneous element startup, reducing inrush current demand and extending equipment life.

Key Features

• 24V control voltage for compatibility with standard low-voltage thermostat circuits
• SPST (Single Pole Single Throw) contact configuration for straightforward wiring
• Normally Open (N/O) contact operation — contacts close upon coil energization
• Genuine Rheem-Ruud OEM replacement part (SKU: 425086)
• Designed for electric furnace and heat strip sequencing applications
• Ensures staged heating element activation to reduce electrical inrush current
• Reliable construction for long service life in residential and light commercial systems

Application

This sequencing relay is a direct OEM replacement for compatible Rheem and Ruud electric furnaces and air handlers. Always verify compatibility with your specific model number before installation. Proper sequencing relay operation is essential for safe, efficient electric heat performance.

Why Choose OEM?

Using a genuine Rheem-Ruud replacement part ensures exact fit, proper electrical ratings, and maintains the integrity of your equipment warranty. Aftermarket substitutes may not meet the original design specifications.
