I guess it depends too on your definition of a "circuit breaker". When I look up the definition in Article 100 I would say "No circuit breakers don't have to have handles". It could be a device that will be resetable by pushing a button.

if memory serves me right, UL standards require that a breaker have some means of indicating a trip, as well as re-setting it. As another mentioned, there are breakers that use a push-button for this, rather than a handle.
