Consequently, the section dimensions and the width of the cable chamber may be selected independently of the section diversity. Fuse-switch disconnector section with Rittal NH slimline fuse-switch disconnectors The fuse-switch disconnector sections for NH slimline fuse- switch disconnectors with 185 mm bar centre distance on horizontal busbar systems in the centre rear section have only been tested by Rittal with Rittal NH slimline fuse-switch disconnectors and meet the requirements of IEC 61 439-2. It is possible to use NH slimline fuse-switch disconnectors from other manufacturers. However, these have not been tested to the standard by Rittal. The maximum admissible rated operating current of the NH slimline fuse-switch disconnectors with due regard for the NH fuse insert used and the minimum connection cross-section may be taken from Table 7.
