Note 1: Models made by Toshiba Industrial Products and Systems 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.
