Notes: The KW selections above are shown for convenience. A full selection of KW ratings from 1 to 1600 KW is available by entering the desired KW into the model number. For alternate voltages including 415, 575 and 600 volt, please consult factory.
Electrical
KW x 1000 ÷ 1.73 = Amps 3 Φ Volts
KW x 1000 = Amps 1 Φ Volts
6
Example: 150 KW at 480V 3F
150 x 1000 ÷ 1.73 = 180 Total Amp Draw 480
180 ÷ 48 Amps max circuit rating = 3.75 Round up the number of circuits to 4
Note: Each branch circuit is rated at a maximum of 48 Amps and each circuit is typically operated as an independent temperature step.
