Except for the sticker?
I personally think those 280Y/120 are a waste of money in a 240V facility. They are great of course when you have 480Y/277 incoming, but total waste @240.
Just buy a three pole and grab two legs. Balancing as you go, of course
Yeah IIRC some breaker lines don't have straight rated 2 poles and they will tell you to use a 3 pole. For bolt on 240 breakers, you could go to a 480 breaker, for example a BQD (for Siemens).
Because that is a standard label, the custom portion in the center is only factory filled in when specially ordered. Can't speak so much for Eaton products but Square D is this way. Most what I get will be from stock and won't have any custom information, just the 240 volt maximum ratings and similar warnings about when used for delta with or without a high leg. If you want it to actually be marked 208/120Y you generally need to special order it and not buy it from stock.
I find it hard to believe there wouldn't be some sort of barrier between each of the main lugs also, unless those were not factory installed or did not use proper main lugs kit of some sort.
Whether that is proper might depend on exactly what you are supplying. If they using two breakers without handle tie to supply a three pole circuit, that is wrong. If they are supplying a unit that is intended to be supplied by two circuits there may not be anything wrong at all. See a lot of air handlers with heat strips that require more than one circuit to supply them.
Decades ago, I used to order Square D NQO and NQOB factory assembled panels where they would only provide bus connections to A and C in part of the panel, like standard 1 phase, and the A, B, and C phases in the rest of the panel. I got to tell them how many of each I wanted.
Or you can scribble on it with a Sharpie. I have seen that many times.
Still can custom order bus arrangement with NQ. I had one a couple years ago that wasn't what I wanted because of a misunderstanding when my sales rep entered the order. I wondered why it was taking so long for it to arrive when they usually just send me stock items for panels similar to what I wanted and let you assemble the panelboard in the field. I wanted a three phase panel with main breaker and with feed through lugs. He called me back at one point and asked if this was going on a high leg system, I said yes - that is where the confusion started. He ended up ordering it with all spaces as "120 volt prepared spaces" which told Square D - we need three phase bus with main breaker and sub feed lugs, but need A and C phase only for the branch breakers. I could not plug/bolt on a three pole breaker and get all three phases in that panel. only main and sub feed lugs had B phase bus connection.
