Abstract: A load interrupter, especially to be mounted on a busbar includes a housing and a cover that is hinged thereto, a snap switch mechanism for establishing or interrupting an electrical connection between corresponding contacts. A control lever for switching between a current-carrying operation and a current interrupting operation, and a control mechanism which, depending on the position of the control lever, releases or blocks a release element for a displacement. The release element being coupled to a locking device which is arranged in such a manner that it can be engaged with or disengaged from the cover.

Abstract: The invention relates to a load-break switch, in particular for mounting on busbars, comprising a housing and a cover arranged pivotally thereon, a snap switch mechanism to produce or to interrupt an electrical connection between associated contacts, and an actuating lever for switching between a current operation and a current interruption operation, a control mechanism which, as a function of the position of the actuating lever, frees or blocks a release element for a movement, the release element being coupled with a locking device which is arranged such that it can be engaged with or disengaged from the cover.
