* If export to the U.S. or Canada or compliance with UL/cUL
standards is required, you need to use wires and breakers
specified in the UL/cUL standards. For details, see "1.7
Compliance with UL Standards".
* The models described in the table are examples of selection.
When using the device, choose a model that has appropriate
breaking capacity and sensitive current by taking short circuit
current and relevant laws and regulations into consideration
based on the rated current shown in the table.
* The applicable motor capacity is a selection example when
Hitachi IE3 4-pole motor model of 60HZ 400VAC (400V class) is
used.
* For the power line diameter, see the "Power line" column in the
table shown in "7.5.4 Recommended Wire Diameter, Wiring
Tools, and Crimping Terminals".

* The electric durability ensured when the magnetic contactor is
used in AC-1 class is 500,000 times, while emergency stop
during motor operation is 25 times.
* If there is emergency stop during motor drive or commercial
operation is performed, choose the magnetic contactor on the
motor side in AC-3 class against the rated current of motor.
* If the rated capacity of inverter is larger than the motor capacity,
choose instruments based on the inverter model.
