<strong>Chapter</strong> 3, Accessories and Spare Parts.<br />
Maximum external diameter of the conductor insulation: 3.6 mm.<br />
For conductor cross-sections ≤ 1 mm² an "insulation stop" must<br />
be used, see <strong>Catalog</strong> LV 1, <strong>Chapter</strong> 3, "Accessories and Spare<br />
Parts".<br />
1) When connecting cable lugs to DIN 46235, use 3RT19 56-4EA1 terminal<br />
cover for conductor cross-sections from 95 mm² to ensure phase spacing.<br />
2) If two different conductor cross-sections are connected to one clamping<br />
point, both cross-sections must lie in the range specified. If identical crosssections<br />
are used, this restriction does not apply.<br />
