Abstract: A circuit breaker can actuate to a closed condition and to an open condition. An assembly for the circuit breaker can include an obstacle that can be positioned to obstruct one form of actuation while permitting another form of actuation. The obstacle can be moved from the obstructing position to allow multiple forms of actuation. The obstacle may permit manual actuation of the circuit to an open state in any position.
