5.2 In-line switch-disconnectors
SASIL plus with fuses
Cubicles with pluggable in-line switch-disconnectors can
also be equipped with SASIL plus in-line units (Fig. 5/3)
produced by Jean Müller.
Rating data of the vertical distribution busbar SASIL
plus
The vertical distribution busbars with the phase conductors
L1, L2, L3 are arranged at the back of the cubicle. The PE, N
or PEN busbars are arranged in the cable connection com-
partment. In the case of 4-pole feeders, the N conductor is
allocated to the phase conductors L1, L2, L3 at the back of
the cubicle. The vertical distribution busbar is covered test
finger proofed (IP2X). The rated data are stated in Tab. 5/8.
Rating data of the SASIL plus cable feeders
Apart from the space requirements for additional built-in
elements (Tab. 5/9), the derating factor stated in Tab. 5/10
is to be set for determining the permissible operating
current of a fuse link. The space requirements for the cable
feeders of the different in-line units depend on the nominal
device current (Tab. 5/11).
