Web5 jul. 2011 · Hi, i'm a little confused about the way to calculate the amp of the circuit breaker for a three-phase system. If i have a power of 11.5 kW and voltage of 400V, what size circuit breaker is needed for three-phase system. My calculation was 11500/(1.732x400) = 16.6 Amps per phase ... 16.6 x 3 = 49.8 Amps, so i need a 50 Amp breaker. WebP = I x V x PF x 1.732 / 1000. to calculate amps 3 phase heater draw. Again, you don’t have to multiply or divide by 1,000. It depends on whether you prefer watts or kilowatts. Either option will work. Remember that the manufacturer will probably express the heater’s energy consumption in kilowatts.
