Principle of the Prisma Plus solution
Prisma Plus system P simplifies the installation of source
changeover systems.
The “source changeover” solution is an integral part of the Prisma Plus offering and
is designed for all installation cases: 2 or 3 devices side by side or 2 superimposed
devices.
The page opposite shows a few examples of installation in cubicles:
1 normal source/1 replacement source
2 normal sources with coupling (priority and non-priority circuits)
2 normal sources + 1 replacement source with coupling (priority and non-priority
circuits).
Note that our configuration software can be used to produce the switchboard front
panel drawings.
For each source changeover configuration, various combinations of normal and
replacement source circuit breakers and switch-disconnectors are possible:
1 normal source/1 replacement source:
NS630b to NS1600 / NS630b to NS1600
NT / NT
NT / NW
NW / NT
NW / NW
2 normal sources with coupling:
NW / NW / NW
NT / NT / NT
NW / NW / NW
2 normal sources + 1 replacement source with coupling:
NW / NW / NW / NW or NT.
Tables in the catalogue indicate the possible combinations “normal” and
“replacement” devices according to the rating as well as the types of interlocking
available for the different types of devices.
Highly economical vertical configurations are possible even for the largest devices.
In this case, interlocking may be:
mechanical by cable + motor mechanism
via rotary handles (for NS630b/1600 only).
To define the number of modules required to install superimposed devices, all you
have to do is add up the number of modules required for each device with:
its connections
its cover and its partitioning.
For combination possibilities and installation details, refer to the “Compact, Interpact
and Masterpact source changeover systems” catalogue ABTED201149EN or
ABTED201149FR.
