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.
