13. CHARACTERISTICS
13.5 Inrush currents at power-on of main circuit and control circuit
The following table indicates the inrush currents (reference data) that will flow when the maximum permissible
voltage (200V class: 253VAC, 400V class: 528VAC) is applied at the power supply capacity of 2500kVA and
the wiring length of 1m. Even when you use a 1-phase 200 V AC power supply with MR-J3-10T to MR-J3-70T,
the inrush currents of the main circuit power supply will be the same.

Since large inrush currents flow in the power supplies, always use no-fuse breakers and magnetic contactors.
(Refer to section 14.10.)
When circuit protectors are used, it is recommended to use the inertia delay type that will not be tripped by an
inrush current.
