Both the RCS-8V and the Ratpak use an indentical looking relay with the same 
part number on them.  It's possible that they are a standard part that has 
been customized differently for the companies, but there is certainly 
nothing obvious to distinguish the two relays.  I had the two side by side 
and looked them over pretty carefully (same PCB mount packaging, same form X 
shorting bar configuration and same coil voltage).  As far as I can tell, 
both companies use the same "custom" relay.

BTW, the relays advertised on the Array Solutions web site for $45 do not 
look like the relays in the Ratpak that I saw.  The advertised relays are 
rated at 10KW and appear to be a heavier duty relay.  The ad for them claims 
a 20 mm contact gap (~3/4"), but that doesn't seem possible from the photo 
and the relay dimensions of  2"x1"x2".
