Abstract
As described above, a withdrawable interlock device of a vacuum circuit breaker according to the present disclosure may locate the second lever between the link and the moving plate, and thus the second lever may be engaged with an outer side of the first lever in a state that the control power connector is coupled to the control power plug not to move the moving plate through the second lever so as to maintain a state that the fitting protrusion is fitted into the fitting groove, thereby having an effect of preventing the circuit breaker body from being separated to the outside of the cradle in a state that the control power connector is coupled to the control power plug to supply power.
