ï‚Ÿ Applicable motor capacity is based on Hitachi 200 VAC (for 200 V class)/400 VAC (for 400 V
class), 60 Hz, 4 pole IE3 motor.
ï‚Ÿ If exports to the U.S. or Canada, or compliance with UL,cUL standards is required, the wires and
circuit breakers specified in the UL,cUL standards must be used. For details, refer to "1.4

ï‚Ÿ Device model name on above table shows example selection. The device selection should be
based on rated current, short circuit current capability and accordance to the local electrical
legislation.
ï‚Ÿ For the wire diameter, refer to the "Main circuit terminal block wiring AWG (mm
2
)" column in
"5.3.2 Recommended Wire Diameters, Wiring Instruments, Crimp Terminal".
