Main circuit
400V class
• At inverter ND rating setting
• At inverter LD/VLD rating setting
Note
1.
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.
2.
The applicable motor capacity is a selection example when standard motors 4-pole motor model 60HZ 200VAC (200V class)
is used.
3.
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.
4.
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.
5.
If the rated capacity of inverter is larger than the motor capacity, choose instruments based on the inverter model.
