The motor capacity indicates the maximum capacity of a 4-pole motor driven by all of the inverters in parallel connection.
Selecting the breaker/magnetic contactor
Check the model of the inverter and the converter unit you purchased. Appropriate peripheral devices must be selected
according to the capacity.
Refer to the table below to prepare appropriate peripheral devices.

The motor output indicates the output power of a 4-pole motor at 400 VAC 50 Hz driven by all of the inverters in parallel connection.
Select an MCCB according to the power supply capacity.
(For the use in the United States or Canada, refer to
The magnetic contactor is selected based on the AC-1 class. The electrical durability of magnetic contactor is 500,000 times. When the
magnetic contactor is used for emergency stops during motor driving, the electrical durability is 25 times.
If using an MC for emergency stop during driving the motor, select an MC regarding the converter unit input side current as JEM 1038-AC-3
class rated current. When using an MC on the inverter output side for commercial-power supply operation switching using a general-purpose
motor, select an MC regarding the rated motor current as JEM 1038-AC-3 class rated current.
An air circuit breaker is also applicable in a system in which a 2000 A breaker or higher is applicable.
