con󰈡gured maximum permissible
angle.
5714 Max. negative phase angle CBA 2 -60.0 to 0.0 °
[-7.0 °]
The prerequisite for a connect
command being issued for the CBA is
that the lagging phase angle between
system B and system A is above the
con󰈡gured minimum permissible
angle.
5717 Phase matching CBA dwell time 2 0.0 to 60.0 s
[3.0 s]
This is the minimum time that the
system A/B voltage, frequency, and
phase angle must be within the
con󰈡gured limits before the breaker
will be closed.

Description
3414 CBB close command 2 [Constant] The relay output is energized as long
as the breaker should be closed.
Impulse The relay output is energized for the
closing time pulse.
3403 CBB open relay 2 [N.O.] Normally open.
N.C. Normally closed.
Not used The relay is not used for opening the
CBB.
3416 CBB time pulse 2 0.10 to 0.50 s
[0.50 s]
Breaker pulse duration to close the
CBB.
The time of the pulse output may be
adjusted to the breaker being utilized.
5705 Closing time CBB 2 40 to 300 ms
[80 ms]
The inherent closing time of the CBB
corresponds to the lead-time of the
close command.
The close command will be issued
independent of the di󰈠erential
frequency at the entered time before
the synchronous point.
3405 CBB auto unlock 2 This is used for special circuit breakers
to put the CBB into a de󰈡ned initial
state or to enable closing at all.
Yes Before every close-pulse, an open-
pulse is issued for de󰈡ned duration
(parameter 5708). A CB close pulse is
