3.4.1 

–

 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.
