Electrical switchboards ...
The Prisma P functional system can be used for all types of low-voltage
distribution switchboards (main, subdistribution and final) up to 4000 A,
in commercial and industrial environments.
1
Ametal structure
The switchboard is made up of one or more
frameworks combined side-by-side or
back-to-back, on which a complete selection of
cover panels and doors can be mounted.
2
A distribution system
Horizontal busbars or vertical busbars positioned
in a lateral compartment or at the rear of the cubicle
are used to distribute electricity throughout the
switchboard.
3
Complete functional units
b
a dedicated mounting plate for device installation
b
a front plate to block direct access to live parts
b
prefabricated busbar connections
b
devices for on-site connections.
Each functional unit contributes to a function in the
switchboard.
The functional units are modular and are arranged
rationally.
The system includes everything required for
functional unit mounting, supply and onsite
connection.
The components of the Prisma P 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.
Switchboard design is very simple
1
A dependable electrical installation
The total compatibility of Schneider Electric
devices with the Prisma P is a key advantage in
ensuring a high level of installation dependability.
2
An upgradeable electrical installation
Thanks to modular design, Prisma P switchboards
can be modified easily to integrate new functional
units as needed.
Maintenance operations, carried out with the
switchboard de-energised, are fast and straight-
forward due to easy access to devices.
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, 3 or 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 P
enclosures.
