Advantages of Prisma Plus
switchboards
A dependable electrical installation
The total compat bility 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 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 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 50298, EN 50298, 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 kÂ
rated short-time withstand current Icw: 85 kA rms / 1 second
frequency: 50/60 Hz.
