SIVACON S8 Planning Principles – Cubicles in fixed-mounted design
Equipment rules for 3NJ4 in-line fuse switch-
disconnectors
Arrangement options for the in-line units in the cubicle:
• From left to right with in-line units decreasing in size
• From right to left with in-line units decreasing in size
The specified rated currents are applicable when the 3NJ4
in-line units are equipped with the largest possible fuse
links. When using smaller links, a corresponding utilization
(in percent) is permissible.

Additional built-in elements
If the busbar and cable connection positions in the cubicle
are identical, one of three possible additional built-in
elements (see Tab. 6/3) can be used. The possible arrange-
ments are listed in Tab. 6/4.

Mounting additional built-in elements for 3NJ4 in-line units
of size 00 is possible for cubicles up to degree of protection
IP31 and operation of the main in-line switch-disconnectors
through the door (door with cutout).
The additional in-line switch-disconnectors are operated
behind the door. This arrangement results in a smaller
width of the device compartment (Tab. 6/5). The rated data
of the cable feeders are stated in Tab. 6/6. The connection
is established directly at the switching device from top or
bottom. Due to the restricted connection compartment,
connections with cable cross sections up to 95 mm² are
possible.
