630 A multi-stage bar support
● Support for fixing bars with cross-sections:
– 15 5.
– 20 5.
– 32 5.
– 32 8.
● The orientation of the copper bars makes tightening easier and allows better
circulation of the cables.
● It can be 3-pole or 4-pole, with gauges from 160 to 630 A.
● Mounting on mounting plates (see page
7/10
) or cross-rails (see page
7/36
).
● Electrical characteristics:
– Rated peak withstand current Ipk (kÂ):
• 30 k for 160 A busbar.
• 40 k for 250 A busbar.
• 55 k for 400 A and 630 A busbar.
– Rated insulation voltage Ui = 750 V.
● Material: insulating plastic.
Supply: 1 multi-stage bar support and fixing elements.
● M6 25 self-tapping screws are required for fixing on the cross-rails, not included.

● The following table shows:
– The cross-section of the bars that will be used according to the current-carrying
capacity in the busbar.
– The distance between the bar supports that will be installed according to the rated
short-time withstand current: Icw.
