Double Phase:

  • Watts÷ Volts= Amps - Example: 18,000W ÷ 440V = 40.9 A
  • Amps X Volts= Watts - Example: 40.9Ax 480V = 18,000W
  • Amps X Volts X 1.73 = Watts - Example: 60A x 480V x 1.73 = 49,824W, Example: 18,000W ÷ 240V = 75A

 

Specification :

  • Ratings : Double Phase – 25 , 34, 59, 70, 90, 150, 200 , 250, 300 Amperes
