
Assumes the use of an IPM motor MM-EFS/MM-THE4 or a Mitsubishi 4-pole standard motor with the
power supply voltage of 400 VAC 50 Hz.

Select an MCCB according to the power supply capacity.
Install one MCCB per inverter.
For the use in the United States or Canada, provide the appropriate UL and cUL listed fuse or UL489
molded case circuit breaker (MCCB) that is suitable for branch circuit protection. (Refer to the
Instruction Manual (Startup).)

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 motor driving, select an MC regarding the inverter input side current as JEM1038-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 JEM1038-AC-3 class rated current.
NOTE
• When the inverter capacity is larger than the motor capacity, select an MCCB and a magnetic contactor according to the
inverter model, and select cables and reactors according to the motor output.
• When the breaker on the inverter's input side trips, check for the wiring fault (short circuit), damage to internal parts of the
inverter etc. The cause of the trip must be identified and removed before turning ON the power of the breaker.
