In a circuit breaker, the movable contact carrying contact arm is pivotally connected to the contact carrier which pivots on the circuit breaker frame; the contact arm is stamped copper; the contact arm carrier pivot connection includes a pin passing through the walls of the carrier and with respect to which the contact arm pivots; also, improved means for establishing pressure of movable contacts.

Circuit breaker contact arm and attachment means

A rotary handle operator mechanism is fixedly mounted in an enclosure having a circuit interrupter mounted therein on the rear wall thereof. The mechanism includes a main handle disposed outside the enclosure for manual operation and being keyed to a cam unit engaged with the circuit breaker handle. A latch unit, including a cover latch section, is provided with a notch formation and a cam formation that cooperate with a forwardly extending pin of the cam unit to provide a switch interlock and a cover latch release.

Circuit breaker operator with defeates interlock mechanism

A rotary handle mechanism for operating a switch device secured to the rear wall of an enclosure is mounted separate from the enclosure cover and extends through a cover opening to be operable from outside of the enclosure when the cover is closed. The mechanism is designed so that the elements thereof may be assembled selectively for operation within an enclosure having a cover that is hinged along one or the other of its edges.
