Busbar systems (100/185/150 mm) 1 Busbar system 100 mm bar centre distance The busbar support is designed to accommodate bars up to 60 x 10 mm Tested for applications with rated operating currents of up to 1250 A and max. 110 kA peak short-circuit current. The busbar system with 100 mm bar centre distance is used for mounting NH fuse-switch disconnectors, sizes 00, 1, 2 and 3, as well as NH slimline fuse-switch disconnec- tors, size 00. When using inserts, this can be reduced to 50 x 10 mm, 40 x 10 mm or 30 x 10 mm. 2 Busbar system 185 mm bar centre distance The busbar support is designed to accommodate bars up to 80 x 10 mm Tested for applications with rated operating currents of up to 1600 A and max. 155 kA peak short-circuit current. The busbar system with 185 mm bar centre distance is mainly used for mounting NH slimline fuse-switch discon- nectors, sizes 00, 1, 2 and 3. Inserts enable this to be reduced to 60 x 10 mm or 50 x 10 mm. The special design of the busbar support facilitates seamless top mounting in the vicinity of the support. In addition, the individual mod- ules of the busbar support can also be used as single-pole supports for PE, PEN or neutral conductor applications. 3 Busbar system 150 mm bar centre distance Multi-terminal busbar system for two conductors running parallel to one another. This facilitates the connection of cables, lines and laminated busbars using connection plates, with no drilling required. Tested for applications with rated operating currents of up to 3000 A and max. 155 kA peak short-circuit current. The busbar system is the simplest way of distributing high currents up to 3000 A over two parallel flat copper bars. Thanks to the 10 mm spacing pieces, flat copper bars 60 x 10 mm may alternatively be used. This system is used primarily in systems where no direct mounting of equipment or adaptors is required. Two support variants are available with 150 mm bar centre distance: 2 x 3-pole up to 2500 A 2 x 3-pole up to 3000 A Rittal Technical System Catalogue/Power distribution 2 - 34
