[RE-wrenches] Recommendation on DC Breaker

[Jason Szumlanski]

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 DIN rail breakers on Amazon are a dead cheap
option and worth considering, too.
