3 Presentation Electrical switchboards up to 4000 A PD eps 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 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: b a dedicated mounting plate for device installation b a front plate to block direct access to live parts b prefabricated busbar connections b 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. PD390150_SE_R.eps Functional units are arranged rationally, one on top of another. 26

Advantages of Prisma Plus switchboards Electrical characteristics A dependable electrical installation The 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 and 2 and benefits from the combined experience of Schneider Electric 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 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 and 2. Use of the components in the Prisma Plus functional system ensures the creation of switchboards complying with standards IEC 50298, EN 50298, IEC and 2, EN and 2, as well as local versions with the following electrical characteristics: b rated insulation level of main busbars: 1000 V b InA (A): 3520 A b rated peak withstand current Ipk: 220 kâ b rated short-time withstand current Icw: 100 ka rms / 1 second b frequency: 50/60 Hz. 27

8 Distribution Form 1 electrical switchboards Main distribution Presentation Decisions concerning the Form of separation and the degree of protection are the subject of an agreement between the manufacturer and the user. Form 1 configuration Covering of upstream and downstream terminals on all devices. DD eps 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 features that 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 removed b keylocks on doors, some of which provide access to live parts b the systematic installation of terminal shields on Compact NSX circuit breakers and Interpact INS and INV switch-disconnectors b covering of the upstream and downstream terminals on the incoming device so that operators are perfectly safe at all points in the switchboard when the incoming device is off (open). What is more, Prisma Plus offers different levels of partitioning to create separations inside the cubicles and thus create Form 2, 3 and 4 electrical switchboards. Electrical switchboards must meet the degree of protection IP2X to comply with standard IEC and 2. Dd eps Covering of the connection between an incoming device and lateral busbars The protection of life and property is ensured by: b the systematic installation of terminal shields on Compact NSX circuit breakers and on Interpact INS and INV switch-disconnectors (see the pages on the functional units) b covering of the upstream and downstream terminals of the incoming device.

9 Form 3 partitioning Distribution Main distribution Definition of Form 3 Separation of busbars from the functional units and separation of all functional units from one another. Separation of the terminals for external conductors from the functional units, but not from each other. b protection against contact with live parts b reduction in the risk of faults between the functional units (propagation of electrical arcs, etc.). Dd eps Dd eps The two types of Form 3 separation as defined by IEC and 2. Form 3a. Form 3b. Form 3a Terminals for external conductors not separated from busbars. The functional units are separated from each other and from the busbars, but not the terminals. b Form 3b Terminals for external conductors separated from busbars. The functional units are separated from each other and from the busbars. The terminals are separated from the busbars, but not from each other. Form 3 configuration Prisma Plus offers Form 3b because it provides much better safety than Form 3a, because the terminals are separated from the busbars. DD eps Form 2 switchboard with: b separation of the functional units from one another b separation of the terminals for external conductors from the functional units. Form 3b partitioning. B-40
