PRISMA G
Distribution Boards up to 630A

 

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.
 

A metal 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}

 

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.

 

Complete functional units

Built around each device, the functional unit
includes:
- a dedicated mounting plate for device installation
- a front plate to block direct access to live parts
- prefabricated busbar connections to connect
  devices to the busbar

- 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.

 

 

 

Electrical Characteristics

 

 Comply with IEC 62208 and EN 62208 standards:

PRISMA P
Distribution Cubicles up to 4000A

 

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.
 

A metal 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.

 

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.

 

Complete functional units

- a dedicated mounting plate for device installation

- a front plate to block direct access to live parts

- prefabricated busbar connections

- 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
