Short-circuit capacity

According to the definition of IEC 60439-1, the 1R5G/2R2P–015G/018P VFD models are suitable for the use on the grid with the maximum   expected short-circuit current no more than 5kA at the maximum rated voltage;   the 018G/022P–090G/011P VFD models are suitable for the use on the grid with the maximum   expected short-circuit current no more than 22kA at the maximum rated   voltage; the 110G/132P–500G VFD models are suitable for the use on the grid with   maximum expected short-circuit current no more than 100kA at the maximum   rated voltage.
