Ri4Power Fuse-switch disconnector section with vertical distribution busbar system for horizontally arranged NH slimline fuse- switch disconnectors and device modules The fuse-switch disconnector sections with vertical distribution busbar systems are suitable for accommodating plug-type NH slimline fuse-switch disconnectors of the following brands: ABB, type Slimline XR Jean Müller, type Sasil Siemens, type 3NJ and Device modules from Jean Müller The distribution busbar system may be configured with the following bar dimensions, see Table 4. Resulting from this, the allocated rated currents Inc with a maximum protection category IP 3X for this section type may be used: Table 4: Rated current Inc and short-circuit withstand capacity Icw of the vertical distribution busbar in the NH slimline fuse-switch disconnector section Dimensions Max. rated current Rated short-circuit withstand capacity Icw Rated short-circuit withstand capacity Icw of busbars Inc with support spacing 300 mm with support spacing 500 mm 50 x 10 mm 1000 A 70 kA, 1 sec. 50 kA, 1 sec. 60 x 10 mm 1250 A 75 kA, 1 sec. 50 kA, 1 sec. 80 x 10 mm 1600 A 85 kA, 1 sec. 60 kA, 1 sec. 100 x 10 mm 2100 A 100 kA, 1 sec. 70 kA, 1 sec. The rated currents Inc also apply to the protection category The maximum admissible rated operating current of the NH IP 2X. For the maximum packaging density when populated slimline fuse-switch disconnectors with due regard for the NH with NH slimline fuse-switch disconnectors, the current spec- fuse insert used and the minimum connection cross-section ifications of the respective switchgear manufacturers shall may be taken from Table 5. apply. The NH slimline fuse-switch disconnectors sizes 00 to 3 should be arranged from top to bottom (top = small sizes).
