    Abstract: Improved drawout switchgear comprises interlocking means automatically operable to lock the movable assembly in the connected position with interlock defeating means operable to maintain the interlock means in a defeated position while an operator operates a levering mechanism to lever the movable assembly from the connected position to a disconnected position. The interlock means is connected to maintain the trip structure of the drawout circuit breaker in a tripped condition when the interlock means is in the defeated or non-interlocking position. Improved secondary contact means is provided for connecting and disconnecting control circuits of the switchgear.
