The motor capacity indicated is the maximum capacity applicable for use of the Mitsubishi Electric 4-pole standard motor.
 Selecting the breaker / magnetic contactor
Check the model name of the inverter and the converter unit you purchased. Appropriate peripheral devices must be selected
according to the capacity.
Refer to the following table to prepare appropriate peripheral devices.

The matrix shows the magnetic contactor selected according to the standards of Japan Electrical Manufacturers' Association (JEM standards)
for AC-1 class. The electrical durability of magnetic contactor is 500,000 times. When the MC is used for emergency stops during motor driving,
the electrical durability is 25 times.
When using an MC for emergency stop during driving the motor, select the MC with JEM 1038-AC-3 class rated current for the converter unit
input current. When installing an MC on the inverter output side to switch to the commercial-power supply operation while running a general-
purpose motor, select the MC for the rated motor current according to the rated current against JEM 1038 standards for AC-3 class.
NOTE
• When the converter unit capacity is larger than the motor capacity, select an MCCB and a magnetic contactor according to the
converter unit model, and select cables and reactors according to the motor output.
• When the breaker on the converter unit's input side trips, check for the wiring fault (short circuit), damage to internal parts of
the inverter or the converter unit, etc. The cause of the output shutoff must be identified and removed before turning ON the
power of the breaker.
