Is the hardware the same for the 2/3 phase to vue compared to the 1-phase ?

Fairly confused about the vue units being sold by Amazon, and whether or not I have the wrong version.

Ordered a vue from Amazon, but the one added to the basket was unavailable, and the suggested alternative that arrived today says it is a 2 or three phase vue.

The install instructions on the website seem to say that the units are identical, but the 2-3 phase has extra clamps.  The instructions all start with 2 or 3 phase install example, but have a 1-phase supplemental install instruction file that talks about just connecting a single CT clamp to either the AB or C sockets, and blanking the other two off for a standard UK 1-phase house install.

So is the 2 or 3 phase unit the same hardware as the 1-phase, but with additional clamps included, or is there a difference in the hardware that means it’s not usable on standard home 1-phase electrics if just the single clamp is used ?

In the past most monitors I’ve used work fine on single phase with one clamp, but support 2/3 phase by adding additional clamps, so wondering if the vue gen2 is the same, or if I need to return it (since the 1-phase doesn’t look to be available at present).

The Vue 2 hardware is the same no matter what type of electrical service you have.  Only difference in measuring single, split phase, or three phase is how many mains clamps you attach to the unit, and how you wire the power feed (black, red, blue).  They have bundles to purchase that include various number of mains clamps, and various numbers of circuit clamps.
