Inrush Currents At Power-On Of Main Circuit And Control Circuit - Mitsubishi Electric MR-J5 Series User Manual

5.5
Inrush currents at power-on of main circuit and
control circuit
Since large inrush currents flow in the power supplies, be sure to use molded-case circuit breakers and magnetic contactors.
Page 168 Molded-case circuit breakers, fuses, magnetic contactors
When circuit protectors are used, it is recommended that the inertia delay type, which is not tripped by an inrush current, be
used.
200 V class [G] [A]
The following shows the inrush currents (reference data) that will flow when 240 V AC is applied. Even when a 1-phase 200 V
AC power supply is used with MR-J5-10_ to MR-J5-200_, the inrush currents of the main circuit power supply will be the
same.
