Abstract: A switchgear device including a main unit supporting an operating mechanism, and at least one auxiliary unit, wherein the units each includes a rotary bar mounted in a mobile contact bridge for rotation around an axis of rotation, and two stationary contacts are connected with the mobile contact bridge. The operating mechanism moves a drive rod through an angular path which results in moving all of the mobile contact bridges between an open position and a closed position. A stop, against which the drive rod presses in the closed position, limits movement of the drive rod, and applies a rotational torque to the drive rod to keep it parallel to the axis of rotation.

Abstract: This concerns a four pole molded case circuit breaker having separable main contacts and an operating mechanism utilized to cause the separable main contacts to open and close. A trip unit is provided to actuate the operating mechanism in desirable circumstances. The circuit breaker in this case has four-poles, one of which is a neutral pole. The circuit breaker trip unit has rotatable trip bars therein, one of which is associated with the three-line terminals and one of which is associated with the neutral terminal. If the line terminal trip bar is actuated to move because of a fault to overload in one of the line terminals, only the line terminals will open because the neutral trip bar will not be moved. However, if the neutral trip bar is moved because of a predescribed neutral current value in the neutral conductor all of the contacts including the neutral contact will be opened because of the interlocking arrangement between the neutral trip bar and the line trip bar.
