ABSTRACT:
Load-break switches and current-limiting fuses are often serially connected and placed one above the other. This arrangement is relatively bulky, and involves in particular relatively large requirements in respect to height.
The present invention concerns an arrangement of parts wherein the load-break disconnect and the current-limiting fuse are electrically connected in series, but wherein they are arranged spatially in parallel, substantially in coaxial relation, the load-break switch or some of its constituent parts being arranged inside of the current-limiting fuse; or the load-break switch and the current-limiting fuse may be provided with contact means common to both of them.
