The Prisma Plus functional
system
The Prisma Plus functional system can be used for all types of low-voltage
distribution switchboards (main, subdistr bution and final) up to 3200 A, in
commercial and industrial environments.
Switchboard design is very simple.
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.
A distribution system
Horizontal busbars or vertical busbars positioned in a lateral compartment or at the
rear of the cubicle are used to distr bute electricity throughout the switchboard.
Complete functional units
Each device is part of a functional unit comprising:
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, one on top of another,
within the enclosure.
The system includes everything required for functional unit mounting, supply and on-
site connection.
The components of the Prisma Plus system 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.
