Prisma Plus

Prisma Plus - a tried and tested modular system

A dependable electrical installation

The total compatibility of Schneider Electric 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 61439-1 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 functions 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 Prisma Plus switchboard is risk-free when carried out by qualified persons in compliance with all applicable safety regulations. Devices are installed behind protective front plates and only the operating handles are accessible. Additional internal separations protect against direct contact with live parts. Terminal shields are mandatory for installation of Compact NSX and Interpact INS/ INV devices in Prisma Plus enclosures.

The Prisma Plus functional System

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. Switchboard design is very simple.

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

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 onsite 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.

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 _, 3 or 4 separation to protect against direct contacts with live parts.Terminal shields are mandatory for installation of Compact NSX and INS/INVdevices in Prisma Plus enclosures.

Electrical switchboards built using the Prisma Plus functional system and Schneider recommendations fully comply with international standard IEC 60439-1.

Electrical characteristics

Use of the components in the Prisma Plus functional system ensures the creation of switchboards complying with standards IEC 50_98, EN 50_98, IEC 60439-1 and EN 60439-1, as well as local versions with the following electrical characteristics:
rated insulation level of main busbars: 1000 V
rated operational current Ie: 3200 A
rated peak withstand current Ipk: 187 kĀ
rated short-time withstand current Icw: 85 kA rms / 1 second
frequency: 50/60 Hz
