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

5.5
Inrush currents at power-on of main circuit and
control circuit
A molded-case circuit breaker and magnetic contactor may fail or malfunction due to an inrush current flowing through the
servo amplifier's power lines (input lines) at power on. Therefore, use products with the specifications described on the
following page.
Page 219 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.
