Abstract
A handle operating mechanism of a multi-pole circuit breaker is provided for operating a pivot handle thereof. The handle operating mechanism includes a fixed portion, a movable portion, a driven portion and a manual portion. The manual portion includes a stem with a first passage, a first connecting device coupled with the outside surface of a panel of an appliance and a second connecting device coupled with the driven portion, wherein the first connecting device is used as a fulcrum and the second connecting device moves along the first passage when the stem is rotated. The stem is rotated to drive the driven portion and the movable portion such that the pivot handle is securely held in one of an on position and an off position.
