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 4000 A, in commercial and industrial environments.

Switchboard design is very simple.A metal structureThe 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 systemHorizontal 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 unitsEach device is part of a functional unit comprising:b a dedicated mounting plate for device installationb a front plate to block direct access to live partsb prefabricated busbar connectionsb 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 inparticular have been designed and tested taking into account device characteristics.This design approach ensures a high degree of reliability in system operation andoptimum safety for personnel.

Advantages of Prisma Plus switchboards

A dependable electrical installationThe total compat bility 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 standards IEC 61439-1 and 2 and benefits from the combined experience of Schneider Electric customers over many years.An upgradeable electrical installationThanks 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 personnelWork 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 NSX and INS/INV devices in Prisma Plus enclosures.Electrical switchboards built using the Prisma Plus functional system and Schneider recommendations fully comply with international standards IEC 61439-1 and 2.

Electrical characteristics Use of the components in the Prisma Plus functional system ensures the creation of switchboards complying with standards IEC 50298, EN 50298, IEC 61439-1 and 2, EN 61439-1 and 2, as well as local versions with the following electrical characteristics:b rated insulation level of main busbars: 1000 Vb InA (A): 3520 Ab rated peak withstand current Ipk: 220 kÂb rated short-time withstand current Icw: 100 kA rms / 1 secondb frequency: 50/60 Hz.

PresentationDecisions concerning the Form of separation and the degree of protection are the subject of an agreement between the manufacturer and the user.

In most installations, Prisma Plus cubicles do not require partitioning. In this case,the switchboard is a Form 1.Safety being one of its foremost goals, Schneider Electric offers options and featuresthat go well beyond the recommendations of the standard.The protection of life and property is a standard feature due to:b front plates that require a tool to be removedb keylocks on doors, some of which provide access to live partsb the systematic installation of terminal shields on Compact NSX circuit breakersand Interpact INS and INV switch-disconnectorsb covering of the upstream and downstream terminals on the incoming device sothat operators are perfectly safe at all points in the switchboard when the incomingdevice is off (open).What is more, Prisma Plus offers different levels of partitioning to create separationsinside the cubicles and thus create Form 2, 3 and 4 electrical switchboards.Electrical switchboards must meet the degree of protection IP2X to comply withstandard IEC 61439-1 and 2.

Form 1 configurationCovering of upstream and downstream terminals on all devices. D

The protection of life and property is ensured by:b the systematic installation of terminal shields on Compact NSX circuit breakers and onInterpact INS and INV switch-disconnectors (see the pages on the functional units)b covering of the upstream and downstream terminals of the incoming device.

Carefully designed in every detail, Prisma Plus cubicles are the solution for all common switchboard configurations up to 4000 A. A reduced number of catalogue numbers facilitates selection, while offering the essential functions such as: b multiple combination possibilitiesb an array of interchangeable cover panels and doors, IP30 or IP55, without adding gasketsb total access bility to all connection points in the switchboardb wide cable compartmentsb high for large capacity (36 modules, each 50 mm high).The discreet design, with simple lines and oval shapes in the RAL 9001 colour, mean Prisma Plus cubicles blend in naturally on all commercial and industrial sites.They offer 36 modules, each 50 mm high, of useful space.

They comply with standard EN 50298.

ps The frameworkThe framework is both light and rigid due to the closed sections used for the uprights. The compact design of the framework means there is 15 % more space available for devices. There are no sharp edges. Assembly is particularly fast with only 12 screws, all directly accessible. Uprights have wing holes every 25 mm. A measuring tape can be hooked to a slot marking the starting point for measurements on the heights required to mount devices. Marks every 50 mm and double marks every 100 mm make it easy to count modules.The floor fixing kit can also be used to level the cubicles.
