Maximum lightning current
I
imp
= 50 kA for
≤
5 ms
(according to IEC 62561-1)
I
imp
= 100 kA for
≤
5 ms
(according to IEC 62561-1)
Note:
• Recommended maximal cross section of connected cable
according IEC 60947-7-2 and IEC 60947-7-1:
16 mm² (6 AWG) copper (tested short circuit current I
cw
= 1.92 kA for 1 s)
• Fastening of thicker cable is acceptable, if the maximum short circuit current I
cw
and
the exposure time is not exceeded and the provisions on cable lug thickness t
cl
are
observed.
