The Siemens HNF361RPV is worth looking into. Quite affordable and reliable
build quality without having to resort to Amazon. It first appears that it’s
limit is 250 vdc but the footnotes indicate 600 once going deeper into the
details. Obviously not a fuse though.

Thanks, all, for the quick recommendations. I believe an isolator like the
IMO is technically all that is needed since it is a current limited circuit
and OCPD shouldn't be required, but the manual calls for a circuit breaker.
That is probably just a semantics issue.
On the other hand, the 1000V
Jay,
I regularly use 1000 vdc rated, 20a breakers. You can buy them on Amazon.
They are din rail mount. 1,2 or 4 pole.

I've used Midnite DC combiners in the past with good results. Since you are
over 150 VDC, I believe you'd need to select the 1000 VDC fuse holder(s)
for your application:

Correction: That was unadjusted Voc. Temperature-adjusted Voc is 316V.

I’d use an IMO disconnect as you don’t have any current limitations.
I think sometimes things get lost in translation.

I am installing an EG4 off-grid 3k inverter for the first time, and the
manual requires a DC circuit breaker on the PV input. It will be a small PV
array with adjusted max Voc around 280V @ Isc 10.6A.
I'm looking for a cost-effective DC breaker and enclosure for this purpose.
