Abstract
The invention relates to a multiphase line fuse module. According to the invention, said multiphase line fuse module comprises a busbar pack (32), interposed between two supporting plates (16, 42), at least one line fuse (52, 66) with an associated AC contactor (54) per phase, said phase assemblies being arranged one on top of the other in front on a small face of the busbar pack (32) having connections (56, 58) on the small face and being electrically connected to the small face connections (56, 68), and a cover closing the phase assemblies on the front side. The invention thus provides a space-saving system for line fuses (52, 66), AC contactors (54) and busbars in one housing, thereby allowing an easy replacement of the wearing parts.
