Instantaneous Protection (INST) 

 
Instantaneous protection is designed to protect against high current short circuits. This protection is independent of time and is set as a multiple of I

r

 

 

 

 
 
 

 

Adjusting I

i

 (Current) 

 
The l

i

 trip threshold tolerance for instantaneous protection is ±20%. 

The instantaneous protection has no adjustable time delay. 
The non-trip time is 10 ms with a maximum cut-out time is 50 ms 
 
The l

i

 can only be adjusted by selecting a pre-defined curve and is set as a multiple of I

r

. Depending on the selected curve and MCCB model there are 

maximum values for I
