Apparatus ( ) for interrupting the flow of current in a power distribution system is disclosed for use with an enclosure containing insulating fluid. The apparatus ( ) includes a housing ( ) formed from insulating material and having a mounting flange ( ) formed along the exterior of the housing ( ). The flange ( ) is located so that the housing extends away from the mounting side and the upper side of the flange. An electrical current interrupter ( ), having electrical input and output ends ( ), is positioned in the housing ( ) so that a portion lies within the portion of the housing extending away from the flange mounting side. An actuator ( ) is mechanically connected to the interrupter ( ) to provide the mechanical actuation required to interrupt the current flow between the input and output ends of the interrupter. When the flange ( ) is attached to the enclosure, the portion of the housing ( ) extending away from the flange mounting side extends into the fluid within the enclosure.
