Q U A L I T Y   T H R O U G H   E X P E R I E N C E  

The Prisma Plus functional system can be used for all types of low-voltage

distribution switchboards (main, subdistribution and final) up to 3200 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 at the

rear of the cubicle are used to distribute 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 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.

 

Advantages of Prisma Plus switchboards

 

A dependable electrical installation

The total compatibility of Schneider devices with the Prisma Plus system is a key

advantage in ensuring a high level of installation dependability.

System design has been validated by type tests as per standard IEC 60439-1 and

benefits from the combined experience of Schneider customers over many years.

An upgradeable electrical installation

Thanks to modular design, Prisma Plus 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.

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 NS and INS/INV devices

in Prisma Plus enclosures.

Electrical switchboards built using the Prisma Plus functional system and

Schneider recommendations fully comply with international standard

IEC 60439-1.
