Circuit prospective fault current calculator, PFC calculator.

Calculate the PFC fault current (kA & Amps) single phase and three phase PFC from the voltage and Ze or Zs earth loop impedance values.

Enter any two values to calculate the third.

Features:
- Calculate PFC (from Zs/Ze & Voltage)
- Calculate Zs / Ze (from Voltage & PFC)
- Calculate Voltage (From PFC & Zs/Ze)
- Calculate to PFC kA and PFC Amps single & three phase.

A useful electrical PFC calculator to calculate the PFC kA to check the correct MCB kA rating is selected or circuit fault current.

How to use:
1) Enter ANY two values to calculate the third.

Calculate the circuit Prospective Fault Current from the Zs / Ze and voltage values.
