I found this brochure which lists all models and their feature set:Just a note: this three-phase PDU is metered but not "managed" like the single-phase one which the post was started about. I don't know which features are omitted on "metered" PDUs - possibly it's not switched? And possibly it's not metered-by-outlet? Eaton's website is unfortunately difficult to find details on...
I waited a while on the fence to buy these and ended up paying a lot more than OP as a result. Oops.
The 106-10 are all sold out now...
