230VAC Single Phase Derating for Three Phase Controls
Single phase AC input power can be used to power a three phase control.
However, the continuous and peak current ratings of the control must be
reduced by 35% (derated).

C copper wire, 1% line impedance. Higher
temperature, smaller gauge wire may be used per NEC and local codes.
Recommended fuses are based on 40
°
C ambient, maximum continuous
control output current and no harmonic current.
