Automatic doubling or Overcurrent thresholds on current inrush

For some of the phase Overcurrent functions it is possible to have the set trip level [Is] automatically
doubled when strong inrush current is detected.
If at circuit Breaker switch-on (i.e. when the input current rises from zero to a minimum measurable value)
the current increases from 0 to 1.5 times the rated value [In] in less than 60ms, the set minimum pick-up
level [Is] is dynamically doubled ([Is]

→

[2Is]) and keeps this value until the input current drops below

1.25xIn or the set time [t2xI] has elapsed.
This functionality is very useful to avoid spurious tripping of the instantaneous or short-time delayed
Overcurrent elements that could be experienced at switch-on of reactive loads like Transformer or
Capacitors.
