Max inrush for a transformer.

Absolute Max is the inrush value expected if you energize the Transformer when the Voltage sine wave is equal to zero, inrush will occur in the first ½ cycle so there is a very slim chance customers will hit this value.

Practical Max: This is most likely the maximum Inrush current the customers will see when they energize the transformer .

If you compare the current values at time equal to  0.0083 sec. (1/2 cycle) you will conclude that the inrush event will not be seen by the breaker.
