1)
Special DC voltage on request.
2)
Take the short-circuit withstand capability of the instrument transformers into account separately.
For data on the individual switching devices, see ABB switchgear handbook or the instruction manual for the
switching device concerned, as listed under 7.1.
2.2 Resistance to internal arc faults
The resistance to internal arcing faults is 50 kA 1s.
Criteria 1 to 6 of PEHLA Directive No. 4 (in con-
junction with VDE 0670 part 6 and IEC 60298) are
fulfilled. Depending on the configuration of the
panels and/or the switchroom conditions (e.g. low
ceiling height), additional measures may be
necessary to ensure compliance with criterion 5.
