3 Phase Motor Circuit Breaker Sizing Calculator
The calculator is designed to accept the total line voltage and current of the combined three cables. The equation for the area of a single wire is modified to: A = \frac {\sqrt 3 I \varrho L} {V} A = V 3I ϱL. The factor of \sqrt 3 3 is needed to convert between the system's phase current and line current.

1. The Type of Motor Motors typically fall under two categories: High Tension (HT) motors Low Tension (LT) motors High Tension (also called High Voltage) motors usually supply above 1.1 kV and have a rating that is more than 150 kW. In contrast, Low Tension (or Low Voltage) motors usually supply below 440 V and have a rating of less than 150 kW.

How To Calculate 3 Phase Motor Amps
For example, if you have a 3-phase motor with a power rating of 10 kW and a voltage of 400V, the FLC would be calculated as follows: 10 kW * 1.25 / 400V = 31.25 Amps. Once you have the FLC, you can use it to calculate the minimum cross sectional area of the cable.
