The recommended molded case circuit breaker (MCCB) must be connected to primary side of each inverter to
protect the wiring system.
Note 1: Models made by Toshiba Industrial Products Sales Corporation are shown.
Note 2: Be sure to attach a surge killer to the exciting coil of the relay and the magnetic contactor.
Note 3: When using the auxiliary contacts 2a of the magnetic contactor MC for the control circuit, connect the
contacts 2a in parallel to increase reliability.
Note 4: When a motor is driven by commercial power supply using commercial power supply / inverter switching
circuit, use a magnetic contactor appropriated AC-3 class the motor rated current.
Note 5: Select an MCCB with a current breaking rating appropriate to the capacity of the power supply, because
short-circuit currents vary greatly depending on the capacity of the power supply and the condition of the
wiring system. The MCCB, MC and ELCB in this table were selected, on the assumption that a power
supply with a normal capacity would be used.
Note 6: For the operation and control circuits, regulate the voltage at 200V to 240V with a step-down transformer
for 500V class.
Note 7: In case of

setting, be sure to select the wiring device for 1 rating up motor.
Note 8: Regarding influence of leakage current, refer to section 1.4.3.
