Circuit diagrams
The circuit diagrams show all the available components with their wiring options.
Fig. 33 to Fig. 39 show some non-binding examples of vacuum circuit-breaker mod-
ules.
The circuit diagrams for the vacuum circuit-breaker module are compiled depending
on your order.
Mechanical manual closing and electrical closing
Fig. 33 Sample circuit diagram – connection via low-voltage interface, 64-pole,
basic version
Electrical manual closing and electrical closing
Fig. 34 Example – circuit diagram with connection via low-voltage interface 64-
pole.
This legend is also valid for the following circuit diagrams.
