Integration of Compact NSX in
Prisma Plus
The Compact NSX range is perfectly
interchangeable
with Compact NSX.
As for Compact NS, installation of Compact NSX devices in a Prisma Plus functional
switchboard is very easy, based on the same functional-unit system:
same mounting plates as for the Compact NSX
same power connections (Polypact distribution block and prefabricated
connections)
identical control connections
identical partitioning (form 2b to 4b)
same modularity (taking into account the safety clearances).
This greatly facilitates extension, maintenance and retrofitting operations in Prisma
Plus switchboards.
Only the front plates have been changed for this new range.

A new front plate for a new circuit
breaker
The front of Compact NSX circuit breakers has an eye-pleasing curved profile,
making Prisma Plus switchboards even more attractive. This change is perfectly in
step with the new cut-out for Prisma Plus front plates (the same cut-out for all types
of controls).

Installation architectures for the
measurement function
As mentioned above, Compact NSX circuit breakers equipped with Micrologic 5/6 A
or E trip units provide measurements that can be read on the FDM 121 display
module or directly on the circuit breaker. This makes it possible to optimise the space
required by the functional unit.
Installation times have also been reduced with respect to a system with current
transformers.
What is more, installation and connections are made easier because the FDM 121 is
installed just like the 96 x 96 mm Power Meter PM devices:
direct cut-out in a plain door
on a front for one or four 96 x 96 devices in the functional unit or the 300 mm wide
duct door.
Note:
a single 24 V DC power supply is required to power both the FDM 121 display and the
Micrologic trip unit.
