8.3.6.1
Application
M13544-3 v7
The interlocking for bus-section disconnector (A1A2_DC) function is used for one
bus-section disconnector between section 1 and 2 according to figure
A1A2_DC function can be used for different busbars, which includes a bus-section

Signals in single breaker arrangement
M13542-6 v5
If the busbar is divided by bus-section disconnectors, the condition
no other
disconnector connected to the bus-section
must be made by a project-specific logic.
The same type of module (A1A2_DC) is used for different busbars, that is, for both
bus-section disconnector A1A2_DC and B1B2_DC. But for B1B2_DC,
corresponding signals from busbar B are used.
