Inrush Current At Power-On - Mitsubishi MR-JE-10B Instruction Manual

10. CHARACTERISTICS

10.5 Inrush current at power-on

The following table indicates the inrush currents (reference data) that will flow when 240 V AC is applied at
the power supply capacity of 2500 kVA and the wiring length of 1 m. Even when you use a 1-phase 200 V
AC power supply with MR-JE-10B to MR-JE-200B, the inrush currents will be the same.
Since large inrush currents flow in the power supplies, always use molded-case circuit breakers and
magnetic contactors. (Refer to section 11.7.)
When circuit protectors are used, it is recommended that the inertia delay type, which is not tripped by an
inrush current, be used.
POINT
For a servo amplifier of 400 W or less, the inrush current values can change
depending on frequency of turning on/off the power and ambient temperature.
