Full Load Current Calculator

Welcome to our full load current calculator!
For the calculation the full load current of a device or circuit, you will need to know the following information:
The voltage of the circuit (V)
The power rating of the device or circuit (W)
The power factor of the device or circuit (PF)
Whether the circuit is single-phase, 3-phase or DC

ExplanationThe full load current is the amount of current that a device or electrical circuit is rated to carry continuously without overheating or damaging the conductors. Knowing the full load current of a device or circuit is important to properly size the conductors, overcurrent protection devices, and power supply.

3-phase circuits
﻿
I=1000⋅SkW3⋅VLL⋅cos ϕI = \frac {1000 \cdot S_{kW}}{\sqrt{3} \cdot V_{LL} \cdot cos \: \phi} I=3​⋅VLL​⋅cosϕ1000⋅SkW​​
Single-phase circuits
﻿
I=1000⋅SkWVLL⋅cos ϕI = \frac {1000\cdot S_{kW} } {  V_{LL} \cdot cos \: \phi } I=VLL​⋅cosϕ1000⋅SkW​​
DC circuits
﻿
I=1000⋅SkWVLLI = \frac {1000 \cdot S_{kW} } {V_{LL}}I=VLL​1000⋅SkW​​
