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.
