Spacial SFP
Prisma functional system
Introduction
The Prisma functional system can be used for all types
of low-voltage distribution switchboards up to 4000 A,
in commercial and industrial environments.
Switchboard design is very simple Advantages of Prisma system switchboards
1
Ametal structure
made up of one or more frameworks
combined side-by-side or back-to-back.
2
A distribution system
positioned in a lateral compartment
or at the rear of the cubicle are used
to distribute electricity throughout
the switchboard.

devices for on-site connections.
The functional units are modular and
are arranged rationally, one on top
of another, within the enclosure.
The components of the Spacial SFP
and those of the functional units
in particular have been designed
and tested taking into account
device characteristics.
This design approach ensures a
high degree of reliability in system
operation and optimum safety
for personnel.
1
A safe electrical installation
The total compatibility of Schneider Electric devices with the Prisma
system is a key advantage in ensuring a high level of installation
dependability.
2
An upgradeable electrical installation
Thanks to modular design, Spacial SFP switchboards can be
modified easily to integrate new functional units as needed.
3
Total safety for personnel
Work in a switchboard must be carried out by authorised persons in
compliance with all applicable safety regulations. To increase the
safety of personnel, devices are installed behind protective front
plates; only the operating handles are accessible. Additional internal
protection (partitions, barriers) is available to create form 2, form 3
and form 4 separation to protect against direct contacts with live
parts.
Terminal shields are mandatory for installation of Compact NSX
and INS/INV devices in Prisma system enclosures.
