---
Overvoltage protection of Installations Equipment Rotating machines Cable sheaths Application Alternating current (AC) and direct current (DC) Outdoor and indoor
Nominal discharge current I n 8/20 µs
5 kA peak
High current impulse I hc 4/10 µs
65 kA peak
Long duration current impulse
250 A / 1000 µs
Short circuit rating I s
not specified
The thermal stability of the MO surge arrester is proved in the operating duty test with a high current impulse, which gives an energy input of 2,0 kJ/kV (Uc, AC). General data Ambient air temperature
-40 to +40 °C (for higher
values contact manufacturer) Altitude
up to 1800 m (for higher
values contact manufacturer) Frequency of system voltage
