8 Transient contact (-BGB4)
This contact closes momentarily (for > 30 ms) upon
circuit-breaker opening by remote control or by
means of a shunt opening release.
The indication is not given when opening is manual
and local. In this case, a contact (–BGB11) is
activated by the manual pushbutton and cuts out
the closing indication of the transient contact
(-BGB4).
The transient contact is activated by the main
operating shaft, thus the indication is only provided
when the main contacts of the circuit-breaker
effectively open.
