In this case, the number of needed CBBs is three, that is, the first shot's reclosing time
depends on the initiation signal.

Figure 346: Three shots with three initiation lines
If the sequence is initiated from the INIT_1 line, that is, the overcurrent protection
high stage, the sequence is one shot long. If the sequence is initiated from the INIT_2
or INIT_3 lines, the sequence is two shots long.
