Mitsubishi Electric AE-SW Series Instruction Manual page 11

Since fault current owing through the conductors causes large electromagnetic forces, the conductors should be
secured rmly, using the values in the below table as a reference. Max. distance between xing support and breaker
bus bar should be less than 200mm.
Conductor
Breaker
200 mm or less
Supporting xture
Supporting between live parts of
different poles and between the
power supply and load terminals.
Fig. 11-1
When selecting conductors to be connected to the breakers, ensure that they have a suf cient current capacity. Refer to the right table.

For 3200 A or higher, there is no speci cation by IEC (IEC 60947-1). (Speci cation by the manufacturer)
Control circuit terminal block
Tighteing with excessive torque above the specification may cause damages of
terminals and screws.
Be sure to tighten with the specified torque.
After removing screws, make sure not to tighten the screws diagonally.
Be careful not to apply excessive tension to the wirings.
Use a cross-head screwdriver with a diameter that matches the cross-shaped
groove.
