CNI 503 A4.1, 3x440Vac, 5kV, 100A Overview

12.4. Inrush current

The inrush current depends from the mains impedance, the inductance of the surge inductors and the EUT
impedance. The inrush current in the tables below are max. theoretical values and cannot be reached in a real
system.

Theoretical maximum Inrush current for CNI 503 for 50Hz and 60Hz system depends on supply voltage
