Electrical switchboards ...
The Prisma G functional system can be used for all types of low voltage
distribution switchboards up to 630 A, in commercial and industrial
environments.
1
Ametal structure
The switchboard is made up of one or more
enclosures, combined width-wise and/or
height-wise, with a choice of doors (plain or
transparent).
2
A distribution system
A complete offer of centralised or row distribution
blocks, with busbars in duct or on rear of enclosure,
provides current distribution over the full height of
the switchboard.
3
Complete functional units
Built around each device, the functional unit includes:
b
b
a dedicated mounting plate for device installation
b
b
a front plate to block direct access to live parts
b
b
prefabricated busbar connections to connect
devices to the busbar
b
b
cable-running accessories can be clipped onto
the back of double-profile modular rails.
Each functional unit contributes to a function in the
switchboard.
The system includes everything required for
functional unit mounting, supply and connection.
The Prisma G and functional unit components,
in particular, have been designed and tested
according to device characteristics.
This design approach ensures a high degree of
reliability in system operation and optimum safety.

1
A dependable electrical installation
The total compatibility of Schneider Electric
devices with the Prisma enclosure is a key
advantage in ensuring a high level of installation
dependability.
2
An upgradeable electrical installation
Thanks to modular design, Prisma switchboards
can be easily modified 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 protect against
direct contact with live parts.
Terminal shields are mandatory for installing
Compact NSX and INS/INV devices in Prisma
for even more personnel safety.
