The critical sections of that part number are 51 for fast DC and 20.0A
for 20 amps. All the rest define electrically uncritical things like
toggle handle color, mounting hardware color, and the presence or
absence of auxiliary switches.

Based on my study of the PoCo web page the critical numbers in that
breaker's part number are the 61 for fast DC and the 20.0A. It does have
an auxiliary switch, useful for remotely indicating its tripped. Its
significantly larger physically, but a gang of them will mount
beautifully with a copper buss bar on the supply side for a really nice
hamshack (or Airstream) DC power distribution. The one I made years ago
has at least four styles of breakers. And hasn't enough receptacles so I
need to make a larger (or just another one). I ordered 20, before I
recommended their order on this list. Maybe I should have ordered more.
