A range of intelligent circuit breakers
Compact NSX improves management of electrical
installations
In addition to protection functions, the new generation of
Compact NSX moulded case circuit breakers provides new
features (analysis, measurements and communication)
with access to information:
>
>
either directly on the LCD screen of the trip unit to set the
circuit breaker or read themainelectrical values, including
U, I, f, P(W) and E (kWh)
>
>
or on the FDM121 or FDM128 display on the front of the
Prisma P switchboard (duct door with special front plate)
for quick access to a greater wealth of information.
A cable connects the display to the trip unit without any
special settings or configuration, making it easy to
personalise alarms and displays or read event logs and
maintenance indicators.
Integration of Compact NSX in Prisma P
Installation of Compact NSX devices in a Prisma P functional
switchboard is very easy and made of a functional unit
system:
- dedicated mounting plates for Compact NSX offer
- same power connections (Linergy FC distribution block
and prefabricated connections)
- identical control connections
- identical partitioning (form 2b to 4b)
- same modularity (taking into account the safety
clearances).
Installation
A new front plate
The front of Compact NSX circuit breakers has an
eye-pleasing curved profile, making Prisma P
switchboards even more attractive.
Prisma front plates are designed to take into account
all types of controls (toggle, motor mechanism,
rotary handle).
Installation architectures for the measurement
function
Compact NSX circuit breakers equipped with
Micrologic5/6 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.
What is more, installation and connections are made
easier because the FDM 121 or the FDM 128 is installed:
>
>
on 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.
