* Type of system earthing
** Icw: assigned short-time current
*** Ipk: assigned current, admissible peak
† For units with options 12 and 116 use the higher value.
†† Icc/Icf: assigned conditional short-circuit current
The short circuit current stability values given above for the TN system are also valid for IT for units 30RB 302 to 522. For units 30RB 162 to 262 and 30RB 602 to 802
modications are required.
