Select an MCCB according to the power supply capacity.
Install one MCCB per converter.
(For the use in the United States or Canada, refer to
∗2
The magnetic contactor is selected based on the AC-1 class. The electrical durability of
magnetic contactor is 100,000 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 or using it on the motor side during commercial power supply operation, select an MC
with the class AC-3 rated current for the rated motor current.
 Power regeneration mode
To use the converter in power regeneration mode, select a circuit breaker and a magnetic contactor (MC) for the inverter
according to the inverter capacity. For details, refer to the Instruction Manual of each inverter.
Additionally, install a molded case circuit breaker (MCCB) or earth leakage circuit breaker (ELB) with the rating shown in
the following table on the input side of the FR-XCL reactor. For the information of the installation location, refer to
