 Device model name on above table shows example selection. The device
selection should be made in base on rated current, short circuit current
capability and accordance to the local electrical legislation.
 Applicable motor capacity is based on Hitachi 400Vac, 60Hz, 4 pole IE3
motor.
 Refer to the wire gauge table on chapter 2.6 for power line cable.
 Electrical endurance for AC-1 magnetic contactor is 500000 times,
however, for emergency stop in motor operation will be only 25 times.
 Select AC-3 class magnetic contactor for inverter output for application
which has an emergency stop or commercial power line operation.
 When selecting oversize inverter capacity compare to motor rating,
select magnetic contactor according to the inverter capacity
