The insulated flexible bars are tested in a type-tested switchboard environment.
Their design takes into account the switchboard architecture where they are often in
close proximity to a protection device (circuit breaker or fuse) with significant heat
losses.
The sizes for the flexible bars indicated below take into account the heat losses of
Schneider Electric devices in a Prisma switchboard.
Characteristics

Connection between device and busbars
The flexible bars are determined taking into account the connected device, whatever
the internal temperature of the switchboard.
The bar sizes indicated below take into account the derating curves of devices.

To connect a Compact NSX250 to Linergy BW busbars, use a 24 x 5 mm flexible bar (04746).
(2)
The insulated flexible bars is not compatible with Form 2 partitioning (04922).
In this case, use the form 2 restoration kit 04924 (see page B-58).
(3)
In case of use of 32 x 6 insulated flexible bar, please contact Schneider Electric.
