Technical Data
Metal oxide surge arrester without spark gaps.
Direct moulded silicone housing, grey color.
Designed and tested according to IEC 60099-4 Nominal discharge current In 8/20 µs Line discharge class High current impulse Ihc 4/10 µs Long duration current impulse Short circuit rating Is 50 Hz Classification according to IEEE (ANSI) C62.
11 20 kA (pk) 4 100 kA (pk) 1350 A / 2000 µs 63 kA (rms) for 0.
2 s station class high energy
The thermal stability of the MO-surge arrester is proved in the operating duty test according to LD4 which gives an energy input of 13.
