In this case, the number of needed CBBs is three, that is, the first shot's reclosing
time depends on the initiation signal. The CBB sequence is as follows:
INIT_1 (I>>)
INIT_2 (I>)
INIT_3 (Io>)
Shot 1
(CBB1)
1.0s
Shot 1
(CBB2)
0.2s
Shot 2
(CBB3)

Figure 393: 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. On the other hand, if the
sequence is initiated from the INIT_2 or INIT_3 lines, the sequence is two shots
long.
