Hubbell AAR Relay 24V DC

This auxiliary relay operates at 24V DC input and output, designed for use with Hubbell CU300A, CU300M and CU300HD lighting controls. It provides hard-wired switching for fluorescent and incandescent loads within a H-Moss system. The unit is cULus listed and meets ASHRAE 90.1 standards. Buyers needing wireless communication or a different coil voltage cannot use this relay.

Capacity and headroom

The relay functions reliably between 32 and 104 degrees Fahrenheit, covering typical indoor mechanical and electrical spaces. It adds a single switching point to compatible Hubbell CU series controllers without increasing the control voltage. Installations requiring more than one additional relay per controller or a higher contact rating will exceed the intended design.

Included Add-A-Relay kit

The package supplies the Add-A-Relay module itself, ready for direct integration into the existing H-Moss lighting control assembly. No separate mounting hardware, wiring harnesses or configuration software are provided. Electricians must supply conduit, wire and standard hand tools to complete the hard-wired installation.

Questions about this item

Will this AAR Relay work with my existing Hubbell CU300A lighting controller?

Yes, it is compatible with the CU300A, CU300M and CU300HD series controllers.

How can I verify the relay is operating correctly after installation?

The relay switches the connected load when the 24V DC control signal is present and operates within the 32 to 104 Degrees F temperature range.

What comes in the package and do I need any extra wiring components?

The box includes the Add-A-Relay unit; hard-wired connections to the lighting circuit and 24V DC supply must be provided separately.
