14.5 Inrush currents at power-on of main circuit and control circuit

The following table indicates the inrush currents (measurement data) that will flow when the maximum
permissible voltage (253VAC) is applied at the power supply capacity of 2500kVA and the wiring length of
10m.

Since large inrush currents flow in the power supplies, always use no-fuse breakers and magnetic
contactors. (Refer to Section 15.2.2.)
When circuit protectors are used, it is recommended to use the inertia delay type that will not be tripped
by an inrush current.
