Reports on Gloso Circuit Breakers Blowing

Over on the FB pages this weekend there have been more than a half dozen tripped Gloso breakers in 400's.  New owners, 2022 trailers. 
Even worse: these owners, and several more with newer 320's, also,  seem to have never heard of Victron, or the Victron app. 
How can a dealer let an owner drive away with an expensive trailer...and not point out the crucial part of the solar setup?  

I've read about the Gloso, and the discussions about it focus on the surge of charging power from the converter, especially in the case of a depleted battery.  In a couple of the cases this weekend, the Gloso tripped even when the trailer batteries were (allegedly) fully charged.  One appeared to be a short circuit from a wet 7 pin plug.
Is there any data on what low state of charge of the big 400 AGMs that would cause a surge that would trip the Gloso?
Is it possible that there is a "bad batch" of Gloso breakers out there?

    One comment would be . . . .
    'Blown" should be ' Tripped " as the Gloso is reset-able and not damaged. Right?

    Second comment . . .
    Gloso is a common component between the power sources [battery or solar] and the trailer VDC distribution.  So more data on the  Tripping Conditions is needed.

    Thanks, @MuttonChops , I will amend my comment to say "tripped."  Doesn't seem to be any common denominator on the "tripping" conditions.  Of course, it doesn't help that it is happening to owners new to the trailer .

    Most likely, the new owners are bumping the breaker, causing it to trip.  This come up every now and then with new owners on TB400s.
