The PowerPole connectors snap together to make a single connector of
any width you wish. Looks like you can also build NxM array connectors
for a single plug for the whole panel, though they are a bit bigger
than a Molex.

My experience of the PowerPole was with the 75A version in telecoms
power supplies and we used two blue housings (but the cable insulation
was red and blue (or black) for identification. The housings (and
contacts) are "genderless" meaning that you only need to stock one
contact type and one housing housing assuming you are happy with a
single colour (or color). By interlocking the housings you can assemble
a two pole (or more as Tom suggests) connector that is polarised. Once
interlocked they are secure and require deliberate manipulation to
separate. It would be personal choice to use two or more housing colours.

They are a great connector. When they are mated together any arc is
drawn between the tips of the contact and not the final mating surfaces.
They lend themselves to both panel and cable (free) connectors.
