So like I said, although logic may dictate that it will operate at a high
voltage DC level, having not been tested explicitly for that, it does not have
UL listing – we will not use them on the DC side of our installations for that
reason.

I made the comment that they were not listed for use on DC circuits after I had
reviewed the UL testing criteria, and the specifications from the manufacturer
– It was not a lighthearted comment…

This technology has been in use for a dozen years in European equipment and has
been used in many inverters that we install. It creates a gas-tight connection
and is fully vetted through many manufacturers. I don’t think we need to be
concerned about its ability to create a reliable connection
Soladeck has been offering their product with DIN rail mounted terminal blocks
(I forget the manufacturer, Wiedmueller or Phoenix Contact maybe) for years
now, and listed for 600VDC use.

I've replaced breakers with those symptoms and solved the problem.

Not sure what specific design type of CB this is. You guys/gals do know
that most CB's are designed to Failsafe. They will trip before the rating
if there is anything internal that has been damaged or changed. Designed in
for protection.
It is extremely rare that a CB from a quality
I believe the 30-200 A versions of Eaton/C-H’s line of heavy duty DPDT safety
switches are 600 VDC.

Yikes. Didn’t realize that about the ConnectDER. Repeated tripping due to a
fault can certainly damage internal parts and contacts, leading to resistance
and operation and lower than the rated current.

Yep, I've used them before as high voltage array discos. But no double-throw
models exist unfortunately. The IMO assembly looks identical to the ones used
in all Solaredge on-board disconnects. Available in the US from
www.industrialcontroldirect.com [www.industrialcontroldirect.com].

The breaker is actually in a "connectder", a meter collar add-on which plugs
into the meter socket, and the house meter plugs into it. It creates a point of
interconnect outside of the house panel. Unfortunately the breaker itself
cannot be removed and replaced. The entire collar must be.
That's what I expected to find, i.e. evidence of a heat event / loose
connection at the breaker terminals (discolored and / or melted wire
insulation, etc.), no visual evidence or smell.

I'm presuming this is a breaker in a load center.
Breakers fail, that's not unusual. Breakers for inverters undergo constant
load so they will run hot all the time and will be prone to failure.
It may have always been out of tolerance, most applications never push the
breaker close to the limit.
