Horizontal bar support up to 3200 A
● Support prepared for fixing bars in horizontal position.
● Direct mounting to the structure of the enclosure, on the vertical uprights, at any
height, adjustable with a pitch of 25 mm.
● Maximum nominal rating:
– 1600 A for 5-mm bars.
– 3200 A for 10-mm bars.
● The number and the distance between supports, according to the nominal and
short-circuit current, are stated in the enclosed table.
Supply: two insulating bar supports, one metal horizontal support and fixing
elements.

Note:
The current-carrying capacity values in the set of bars are given for an ambient temperature of 35 °C around the busbar.
The nominal rating values are indicated for IP55. The maximum values (3200 A) are achieved with ambient temperatures of less than 35 °C, varying according to
the configuration and position of the busbar.
See enclosed table of current-carrying capacities according to temperature, page
