the time set with the Reclaim time parameter. Furthermore, if the Fourth delay in
SOTF parameter is "1", the Str _ delay shot 4 parameter delays are also activated.
Example 1
The protection operation time is 0.5 seconds, the Fourth delay in SOTF parameter is
set to "1" and the Str 2 delay shot 4 parameter is 0.05 seconds. The protection start
signal is connected to the DEL_INIT_2 input.
If the protection starts after the circuit breaker closes, the fast trip follows after the set
0.05 seconds. The total trip time is the protection start delay + 0.05 seconds + the time
it takes to open the circuit breaker.
