• Only such CBBs that are set for the next shot in the sequence can be accepted
for execution. For example, if the next shot in the sequence should be shot 2, a
request from CBB set for shot 3 is rejected.
• Any CBB that is set for the next shot or any of the following shots can be accepted
for execution. For example, if the next shot in the sequence should be shot 2, also
CBBs that are set for shots 3, 4 and 5 are accepted. In other words, shot 2 can be
ignored.
In case there are multiple CBBs allowed for execution, the CBB with the smallest
number is chosen. For example, if CBB2 and CBB4 request an execution, CBB2 is
allowed to execute the shot.
The auto-reclose function can perform up to five auto-reclose shots or cycles.

It is possible to create several sequences for a configuration.
Auto-reclose sequences for overcurrent and non-directional earth-fault protection
applications where high speed and delayed auto-reclosings are needed can be as
