2.2 Resistance to internal arc faults
The fault withstand capacity is 31.5 kA for 1 s.
The switchgear units have been tested
according to IEC 62271-200 standard (Annex A,
accessibility type A, IAC classification FLR) and
also to PEHLA recommendation No.4. In
individual cases, depending on the
configuration of the switchgear panels and/or
the switchroom conditions (e.g. low ceiling
height), additional measures may be necessary
to ensure compliance with criterion 5.
