A cable interlock actuated by a plunger extended from the back of a draw-out circuit breaker when the breaker is closed, prevents closure of a second circuit breaker by holding it in the trip condition. A shutter which closes to prevent access to power system terminations at the rear of the draw-out circuit breaker enclosure when the breaker is removed, blocks operation of the interlock to prevent tripping of the other circuit breaker.
