Since your rotary switch is switching both line and neutral, there is no reason to have a circuit breaker doing the same thing.

A single pole circuit breaker will work fine.

We use two pole circuit breakers with a interlock to switch between generator and shore power because they in one device switch both line and neutral, and provide overcurrent protection. Two pole breakers are an easy foolproof installation methodology.
