Abstract: Latching means for holding the movable contact arm carriers of a multipole molded-case electric circuit breaker in an open or OFF position while the operating handle is held in an ON position. The latching means is electrically operable from a remote point to release the contact arm carriers and allow them to move to ON position toward which they are biased by a spring of a toggle mechanism when the operating handle is in ON position.

Abstract: THE BRACKET INCLUDES A ROTATABLE CAM MEANS AND IS SECURED TO ONE END PORTION OF A CIRCUIT BREAKER HAVING A SET OF PLUGON TERMINAL JAWS AT ITS OTHER END PORTION. WHEN THE BRACKET AND CIRCUIT BREAKER ARE PLACED ON A MOUNTING PAN OF AN ELECTRICAL PANELBOARD, THE CAM MEANS EXTENDS THROUGH A RECTANGULAR OPENING IN THE MOUNTING PAN IN POSITION TO SELECTIVELY ENGAGE OPPOSITE SIDE EDGES OF THE OPENING UPON ROTATION THEREBY TO MOVE THE CIRCUIT BREAKER TOWARD AND AWAY FROM A STACK OF BUS BARS ON THE PAN.

Abstract: The circuit breaker includes a contact making and breaking assemblage mounted in a housing and having a trip mechanism with a trip lever carrying a indicator. The housing has an opening through which the handle of a manual operator extends. The handle has a dust shield which underlies the opening and which has a window with a lens therein. The lens is exposed for viewing from the exterior of the housing when the operator handle is in ON and TRIPPED positions, respectively. Upon tripping of the trip mechanism, the trip lever is moved so as to dispose the indicator close to, and in alignment with, the lens and window for indicating the tripped condition. The lens and operator are suitably notched for permitting passage of the indicator into and out of alignment with the window.
