Abstract
Draw-out circuit breaker apparatus is taught with an interphase barrier for metal enclosed switchgear. The interphase barrier includes a unitary member which is mounted on wheels so that it may be partially withdrawn when the circuit interrupter draw-out element is withdrawn thus allowing pivotal shutter members to be moved into position in front of the spouts or bottles of the high voltage terminals of the metal enclosed system. When the movable draw-out element is reinserted in its fully connected position the barrier moves flush with the previously described spouts as the shutters rotate upwardly and downwardly to accommodate insertion of the terminals of the movable circuit breaker into the complementary stationary high voltage terminals.
