what stands out about this relay is the Functional Devices, Inc. name on the package.
RIBU1S Enclosed Pilot Relay 10 Amp 10-30 VAC/DC/120 VAC Coil NEW
You will find that the RIB brand sits cleanly on the side, and the markings remain easy to read.
A nice touch is the clear markings, which make wiring this power relay feel simple and safe.
I like seeing Functional Devices, Inc. listed as the brand; it feels reassuring and familiar.
