1) Prospective short-circuit current < 0.4 kA.
1) If two different conductor cross-sections are connected to one clamping
point, both cross-sections must lie in the range specified. If identical
cross-sections are used, this restriction does not apply.
2) With conductor cross-sections of ≤ 1mm
2
an "insulation stop" must be
used; see "Accessories", "Contactors and Contactor Assemblies".
3) For corresponding 8WA2 803 or 8WA2 880 opening tools
see "Accessories".
