The short-circuit withstand capacity of the instrument transformers must be taken into account separately.
For individual switching device data, see the instruction manual for the relative switching device, as
listed under 7.1.
The fault withstand capacity is as follows:
The switchgear units have been tested according to IEC 62271-200 standard (appendix AA, class A,
criteria 1 to 5) and also to PEHLA recommendation no. 4.
In individual cases, depending on the configuration of the switchgear panels and/or the switchgear
room conditions (e.g. low ceiling height), additional measures may be necessary to ensure compliance
with criterion 5.
