6.3 Connecting the control circuit

Manual, 08/2017, L1V30368969104A-02

Figure 6-78 Installing size 2000 A to 3200 A (4-pole)

Connect the main circuit as described in the sections Connecting current ratings 250 A to

1600 A to the main circuit (Page 46) o r Connecting current ratings 2000 A to 3200 A to

the main circuit (on the line side) (Page 55).

Note

On the 3KC8 transfer switching equipment of sizes ≥ 2000 A, the accessories must be

attached between the two terminals that are connected using the copper bar connection kit.
