Abstract: A motor starter unit is mountable selectively on opposite sides of a stack of bus bars of an electrical panelboard and includes a reversibly positionable circuit breaker operating mechanism. Interlocks are provided to prevent opening of a cover of the motor starter unit when a handle of the operating mechanism is in ON position, unless an interlock-defeating screw is first turned, and to prevent movement of the handle to ON position when the cover is open.

Abstract: A generally U-shaped driving member has a first leg portion pivotally mounted on a bracket secured to a side wall of an openfront box and a second leg portion pivotally associated with a base member formed of insulating material and mounted on a rear wall of the box. An operating handle is pivotally mounted between the bracket and the side wall and is provided with a tang extending through an arcuate slot in the bracket. A tension spring is connected at one end to the tang of the handle and at the other end to a bight portion of the U-shaped driving member. The first leg portion of the driving member has a tang extending through a slot in the bracket into an aperture provided in the handle. An interlock member is reciprocally mounted between the bracket and the side wall and driven by the tang of the handle. The second leg portion of the driving member is provided with a slot in which a driving boss of a blade actuator pivotally mounted in the base member is received.

Abstract: An electrical switch arranged to be mounted on the rear wall of a switch box and having a base open at the front and rear with a partition wall between the front and rear. A blade-operating rotor is installable in the base from the rear and held in operating position behind the partition wall initially by a snap spring detent to facilitate installation of the base on the rear wall. Once installed, a flange on the rotor cooperates with the rear wall to retain the rotor in operating position should the spring fail. The load and line connectors are mounted on the front face of the partition wall for ready access when the front of the switch box is open. The switch blades and companion stationary contact jaws are carried by the base at the rear of the partition wall, and are drivingly engaged by the rotor. The blades are arranged relative to the contact jaws, rotor, and base so as to provide a wider contact separation upon opening of the switch than is usual in switches of comparable size.

Abstract: The insulator comprises three molded segments which are mounted in interlocked end-to-end relation along the drive bar. The two end segments are of fixed length, and the intermediate segment is selectable in length depending upon the length of the drive bar which in turn depends upon the width of the switch. The segments are generally U-shaped in transverse cross-section, and are held in position on the drive bar by a flexible strip of insulating material inserted between spaced shoulders on the end segments after the segments are placed on drive bar. Arc shields may be secured to either or both of the end segments.

Abstract: An exterior operating handle is mounted on the wall of the enclosure of an enclosed-type circuit breaker and is drivingly connected to the operating handle of the circuit breaker. The cover is normally latched in closed position by a manually operable latch. Interlock means normally interlock the exterior handle, cover, and enclosure wall in a manner such that (a) when the cover is latched closed, the exterior handle can be operated to open and close the circuit breaker contacts, selectively; (b) when the cover is unlatched and the exterior handle in in ON position, the interlock means becomes operative to prevent opening of the cover; and (c) when the cover is unlatched or open and the exterior handle is in OFF position, the interlock becomes operative to prevent moving the exterior handle to ON position. If the contacts of the circuit breaker become welded together in closed position while the exterior handle is in ON position, and the exterior handle is moved manually to OFF position and the cover is then unlatched, the interlock means, which normally prevent moving the handle to ON position while the cover is unlatched, are defeated for an instant so as to permit the exterior handle to return automatically to ON position, thus preventing a false indication, and then become active again to interlock the cover and enclosure with the exterior handle in ON position.
