White-Rodgers 24A05E-1 Relay

The White-Rodgers 24A05E-1 is a Level-Temp silent operator designed for precise low voltage control of electric heating systems. Operating at 208 VAC, 60Hz, this SPST normally open relay utilizes a thermal element to provide silent switching, making it an essential component for residential and light commercial baseboard or radiant heating applications where noise reduction is critical. This unit features a built-in 45-second delay on break, which prevents rapid cycling and protects the heater elements from premature fatigue. As a direct replacement for the AE-377, it offers a reliable solution for maintaining HVAC line voltage control. Contractors rely on this electric heat relay for its robust construction and ability to handle high amp draws common in electric furnace configurations. Integrating this 24V control relay into your system architecture ensures consistent performance and minimizes mechanical hum during the heat call sequence.

Key Benefits

• Silent Operation: The Level-Temp technology eliminates the loud "click" associated with standard mechanical contactors.
• Delayed Timing: Integrated 45-second delay optimizes heat dissipation and improves component longevity.
• Universal Compatibility: Serves as a standard 208V replacement for multiple obsolete thermal relay models.
• Versatile Mounting: Compact design allows for installation in standard electrical junction boxes or heater compartments.

Common Questions

Can I use the 24A05E-1 to replace a 240V relay?
This specific model is rated for 208 VAC. While some components are dual-rated, always verify your supply voltage to ensure the thermal element operates within its specified parameters for the correct timing delay.

Does this relay require a specific thermostat?
It is compatible with most standard 2-wire or 3-wire 24V thermostats used in electric heating circuits.

Why is there a delay when the thermostat calls for heat?
The thermal expansion design inherently creates a slight delay (approximately 45 seconds) to ensure a soft start and stop, reducing the electrical inrush and mechanical stress on the heating elements.
