The MCCB, MC and ELCB in this table were selected, on the assumption that a powersupply 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 transformerfor 500V class.Note 7: In case of aul=2 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.
