Sqaure D 3-Pole Circuit Breakers

[Trent Tarter]

I don't recall seeing these types of circuit breakers before. I found two of these 3-pole breakers in a small electrical panel in garage. They are 240 volt and appear to go the well pumps/equipment.

Those are 3-phase breakers. I see three main lugs in the first picture. Was this a 3-phase panel?

Hear's a pic of main terminals. Would this be considered a 3-phase panel?

That's definitely a 3-phase  panel and it looks like it's actually wired with 3 phase power, but it's hard to tell for sure without testing the main lugs. 

The strange thing is that little red wire in the middle lug. I'm not sure what they were trying to achieve there.

Yes I came to the conclusion it was a 3-phase panel, the small read wire on middle lug me wondering?

It's pretty safe to say that no matter what the little red wire is, it's wrong.
